An Aerodynamic Study of Bicycle Wheel Performance Using CFD
A methodology is presented to apply CFD to study air flow around a rotating bicycle wheel in contact with the ground. The bicycle wheel studied here is an accurate geometrical representation of a commercial racing wheel (Zipp 404). Reynolds-Averaged Navier Stokes (RANS) and Delayed Detached Eddy Simulation (DDES) results are computed at a range of speeds and yaw angles commonly encountered by cyclists. Drag and side (or lift) forces are resolved and compare favorably to experimental results obtained from wind tunnel tests. Vertical forces acting on a rotating bicycle wheel are presented for the first time. A unique transition from downward to upward acting force is observed as the yaw angle is increased. Flow structures are identified and compared for different yaw angles. It is expected that a more complete comprehension of these results will lead to improvements in the performance and handling characteristics of bicycle racing wheels used by professional cyclists and triathletes.

A Comparative Aerodynamic Study of Commercial Bicycle Wheels Using CFD
A CFD methodology is used to study the performance of several commercial bicycle wheels over a range of speeds and yaw angles. The wheels studied in this work include the Rolf Sestriere, HED H3 TriSpoke, the Zipp 404, 808 and 1080 deep rim wheels and the Zipp Sub9 disc wheel. Wheels are modeled at speeds of 20mph and 30mph, in contact with the ground, using Reynolds-Averaged Navier Stokes (RANS). Drag, vertical and side (or lift) forces are reported for each wheel. Turning moments are also calculated using the resolved side
forces to examine aspects of stability and maneuverability. Drag and side forces over the range of yaw angles studied compare favorably to
experimental wind tunnel results. The previously reported unique transition from downward to upward acting vertical force on the Zipp 404 wheel for increasing yaw angles is observed for all deep rim wheels and the disc wheel studied here. Wheels were also modeled at a critical yaw angle of 10 degrees using Delayed Detached Eddy Simulation (DDES) to examine the transient aspects of flows around moving bicycle wheels. It is hoped that a more complete comprehension of these results will lead to improvements in performance, safety and control of bicycle racing wheels used by amateur and professional cyclists and triathletes.

A Practical Analysis of Unsteady Flow Around a Bicycle Wheel, Fork and Partial Frame Using CFD
CFD is used to study air flow around a rotating bicycle wheel in contact with the ground, extending previous ‘wheel-only’ work on this problem by including the fork, head tube, top tube, down tube, caliper and brake pads. Unsteady simulations, using a Delayed Detached Eddy Simulation (DDES) turbulence model, were run for 9 different wheel and front fork configurations, over 10 different operating conditions (5 yaw angles, repeated for two different speeds, commonly encountered by cyclists), resulting in 90 transient design points.

HyperWorks Improves Development Processes in Automotive Industry
In 2008 PWO Germany (Progress-Werk Oberkirch AG) had to develop and produce a new steel made automotive cross car beam (CCB) for the dash board of a new car. PWO received the CAD model, the design space definition and other pre-defined standards of the component from the customer and developed and produced the fitting cross beam based on this information. PWO used the HyperWorks Suite to develop the component. HyperMesh was used to transfer the CAD model into a FEA model, which was then used to run dedicated analysis and simulation tasks. To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. HyperForm was used to check the production feasibility of the individual components and for metal forming simulation tasks. It was important for PWO to have a software suite available that could cover all simulation tasks within one graphical user interface and licensing system.

A Comprehensive Process for Composite Design Optimisation
Composite structures offer unmatched design potential as laminate material properties can be tailored almost continuously throughout the structure. Moreover, composite laminate can be manufactured to fit the ideal shape of a structure for aerodynamic and other performances. However, this increased design freedom also brings new challenges for the design process and software. It is shown in this paper that optimization technology is well suited to exploit the potentials that composite materials offer.

Innovative Design Analysis Solutions to Handle the Complexity of Modern Structures
This is a press article published by CAD User Magazine in June 2009.

"The signature buildings that architects love to put up these days might be designed to enhance the architect’s reputation along with the skyline of the client city, but their increasing complexities of shape pose significant challenges for the builders. In the first instance such large projects are never single sourced. They rely on close integration between a number of partners, each addressing significant issues. Secondly,
they come with demands for shorter development times with increased pressure to reduce engineering costs (engineering, because of the complexity of the projects, being a major cost element)."

Rapid Airbag Folding Technique for Side Curtain Airbag
TECOSIM has developed techniques which can shorten the folding & packaging process time to a few hours and still achieve the essential airbag deployment performance. We will present methods which rapidly fold a free mesh and allow for rapid shape changes for a detailed folded model. These methods can significantly reduce the turnaround time to incorporate design changes into the working CAE model for side impact and OOP [Out Of Position] studies. This technology can integrate airbag development further into the virtual world to allow ‘CAE led’ design of airbag profiles, chambers and seam lines to be established early in the design phase and establish a fully folded deployable airbag for all virtual phases.

The Use of MBD Modelling Techniques in the Design and Development of a Suspension System
This paper describes the use of Multi-body Dynamics (MBD) modelling techniques in the design and development of a suspension system for a novel autonomous vehicle. The general approach and philosophy is described, whereby MBD techniques are used in conjunction with an independent (parametric) whole vehicle handling simulation. This is supplemented with examples, showing how MotionSolve was used (in tandem with CarSim) to develop the suspension elasto-kinematic geometric properties to meet specific cascaded targets, to optimise a weighing strategy, to predict forces under a variety of quasi-static and dynamic loads, and to estimate response to track inputs.

HUMOS - An FE Model for Advanced Safety and Comfort Assessments
Biomechanics modelling is becoming increasingly accepted as a tool for enhance assessment of vehicle safety, in particular in the field of injury assessment and virtual testing. Firstly, a generic RADIOSS model for safety applications (HUMOS2) is presented and applications are demonstrated. Important tools associated with the scaling, and positioning of the model is also described. Secondly, an innovative model for scaling of human organs (individualization) is presented. The method which employs optimization techniques, identifies critical (optimal) anatomical control points which allow for a best scaled model of the HUMOS2 representing an individual. Finally, some remaining challenges for future human models are discussed and solution paths are described.

Automotive Modal Testing Support and CAE Correlation Using Altair HyperWorks
To derive the natural frequencies and mode shapes of a given structure, the test Engineer has to decide on excitation positions that will efficiently excite all the modes of the structure in the frequency range of interest. Excitation positions are usually decided upon from experience or trial and error methods which can be time consuming and still not capture all of the modes in the selected frequency range. Using Altair HyperStudy and Radioss (bulk), Pre-test CAE analysis has been carried out to identify effective excitation positions before the commencement of modal testing, thereby significantly reducing pre-test lab time.

Delivering Innovation and Intelligence in Product Design
Packaging designers must constantly inject innovations to attract consumers in a constantly evolving and highly competitive market. Keeping ahead of the competition by bringing new and exciting products to market faster whilst maintaining quality, presents a major engineering challenge. A new packaging development process is described, which introduces advanced automated simulation and optimization technology right from the concept development phase. Detailed predictions of primary, secondary and tertiary packaging performance are made possible through use of advanced simulation technology. Design optimization is then employed using the modelling as a virtual testing ground for design variants. The approach provides clear design direction, an opportunity for wider experimentation, helps to improve performance and reduces uncertainty in the development process.

Evolutionary Design in Chassis Technology
This paper details the use of the Thyssenkrupp eDICT process for the design of sheet metal chassis components. eDICT (evolutionary design in chassis technology) is an innovative structured process flow for the design of optimal structures. eDICT uses the optimisation capability of Optistruct with a set of custom tools to guide and translate a design into a production feasible sheet metal solution. Fundamentally it reverses the usual design loop of CAD first then CAE assessment. The function is used to determine the design and the form follows. On recent projects eDICT has produced 25% mass reductions compared to the current series design. eDICT is also able to reduce development times and resource with an efficient solution production right from the outset.

Biomedical Research at the Scripps Clinic: Modeling Orthopedic Implants with Altair HyperWorks
Every year, countless people — regardless of their age or level of physical activity — begin to experience the effects of osteoarthritis, a degenerative joint disease. As we age, the cartilage that cushions the joints begins to deteriorate. The head of the adjacent bones begin to break down from the friction, causing pain in the joint. When the condition worsens and non- surgical remedies are exhausted, surgeons may recommend joint replacement.

Typically, titanium alloy implants are lined with plastics that act as cartilage and are fixed in place with cement or screws by the surgeon. The implants can give patients a new lease on life, dramatically reducing pain and improving mobility. However, questions naturally arise in the patient’s mind: How much range of motion will I have in the new joint? How much strength will I recover? And how long will the new joint last?

      每年,无数病人——无论其年龄或者社会地位——都会受到骨关节炎(一种关节变性疾病)的折磨。而且随着年龄增大,在关节中起到缓冲作用的软骨会被破坏,与之关联的骨骼会开始产生摩擦并导致关节的疼痛。当情况恶化到一定程度且所有非手术的方法均宣告无效时,医生会建议采用关节移植。一种典型方法是将由钛合金和塑料组合制造的人工关节植入体内,并用粘合剂或者螺钉固定。这些人工关节为病人带来了新的生活,大幅度减轻了他们的痛苦并扩展了他们的活动范围。然而,不可避免地,这些接受移植的病人心中总有些疑问:这些人工关节可以带我走多远?我能够恢复多少力量?这些关节可以用多久?

From Incremental Change to Full Design/Validation Leap: A Multidisciplinary Approach to Optimize Safety and Crash Performance
Heavy-duty mining trucks at Hitachi are designed to meet ISO ROPS and FOPS safety requirements, while structures must be as lightweight as possible. The presentation will discuss Hitachi’s design and simulation approach, which consists of an integrated multidisciplinary analysis process. Dynamic analyses, multibody dynamics simulations, including flexible bodies and dynamic simulations are methods applied to optimize performance and vehicle safety.

The author will present examples such as the optimization of a trolley support structure, a kinematics model of a 100-ton truck and the analysis of a trailing arm. Finally, the author will share his thoughts on the important subject of how simulation can better impact the design.

Driving Million Dollar Savings at Ford using Structural Optimisation
The automotive business is a very competitive industry and in today’s markets, leading manufacturers are keen to find ways of reducing costs without compromising either quality or performance. This paper will cover the process of applying OptiStruct software to the re-development of a high volume and high cost plastic PAS (Power Assisted Steering) pump bracket into a much cheaper aluminium alternative. The outcome of this was a lighter, stiffer and cheaper replacement bracket that had the potential, based on the current production engine volumes, to save Ford Motor Company over $1.1 million a year.

Topology Optimization of Aircraft Wing Box Ribs
This paper considers the application of conventional energy based topology optimization methods for design of aircraft wing box ribs. Compared to standard topology optimization work undertaken at Airbus, the topology optimization of wing box ribs posed several additional challenges, mainly due to the wing box ribs being embedded in a redundant wing box structure. Several approaches to solving this problem have been investigated and are being reported as part of this paper, including a global analysis/optimization approach and two local analysis/optimization approaches.

Optimisation Techniques Leading the Development of a Steering Wheel
The early application of structural optimisation in the design of automotive components streamlines the design process and at the same time significantly increases the potential of the final design achieving maximum performance. This paper details the use of optimisation techniques during the development of a steering wheel, to generate an optimised design for cross attribute performance. This was completed in the Altair HyperWorks environment as Altair HyperMesh combined with Altair OptiStruct enables the creation of a parametric model with a multitude of design variables (i.e. size, shape, displacement, stress and frequency) in order to satisfy NVH, manufacturability, durability and crash targets.

Balancing Manufacturability and Optimal Structural Performance for Laminate Composites through a Genetic Algorithm
This paper details the application of a specialised genetic algorithm to reduce the mass of a laminated composite wing rib. The genetic algorithm has been customised specifically to optimise the performance of polymer-laminated composites. The technology allows the mass to be minimized by the removal or addition of plies of various discrete orientations whilst satisfying the structural intent of the component. For the rib structure assessed, the structural constraints consist of limits placed on the displacement, stress (i.e. ply failure index) and buckling behaviour.

The Automatic Calibration and Robustness Assessment of a Complex Engineering Component: Airbag Inflation
This paper describes the application of new technology to achieve automatic calibration and assess the robustness of an airbag inflation model. Calibration of the kinematic response of the airbag is achieved by defining the activity as an optimisation problem. The objective is to minimise the error between the experimental test and numerical simulation curves. Once calibration has been achieved, a unique robustness assessment is performed, which utilises the optimisation technology used in the calibration exercise.
