Applications of Advanced Composite Simulation and Design Optimization
Usage of fiber reinforced composite material entered an new era when leading aircraft OEMs took an unprecedented step to design and manufacture essentially full composite airframe for commercial airliners. Composite structures offer unmatched design potential as the laminate material properties can be tailored almost continuously throughout the structure. However, this increased design freedom also brings new challenges for the design process and software. Moreover, as a relatively new material, composite behaviors are more complex and less fully understood by design engineers. Therefore, reliable simulation for highly complex events like bird strike and ditching can play an important role in shortening the product design cycle. This paper showcases two area of CAE tools for composite applications. On advanced simulation, bird strike simulation with Altair RADIOSS [1] is demonstrated on an aircraft underbelly fairing. On design optimization, an airplane wing structure is designed using an innovative composite optimization process implemented in Altair OptiStruct [1-3]. OptiStruct has seen increasing adoption among aerospace OEMs, as demonstrated in the Bombardier application process described in this paper.

Using HyperWorks to Generate Electrically Large Surface Meshes for Radar Cross Section or Antenna Placement Simulation
Radar Cross Section (RCS) and installed antenna placement are important parameters for aircraft designs. RCS is a measure of how detectable an object, such as an aircraft, is with radar. A large RCS indicates that an object, such as a jet aircraft, is easily detected.

SELEX Galileo used HyperWorks to generate arbitrarily large surface meshes, with defined electrical properties at the element level, for use with electromagnetic (EM) solvers to calculate either RCS of an aircraft or to determine where to place an antenna for optimum performance.

For this case study a fast-jet aircraft with approximately 100 million mesh elements was assessed for radar tracking and avoidance capabilities.

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.

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)."

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.

Hawk T Mk2 - Arrestor Barrier (BAN MK2) Engagement Analysis
As the UK Ministry of Defence (MoD) Design Authority for Aircraft Arrestor Barrier Nets, AmSafe products are used to stop aircraft from over-running the end of the runway. The British Arrestor Net (BAN) Mk2 is suspended across the runway over-run area by two electrically driven stanchions and raised or lowered by remote control from the Air Traffic Control tower.

This paper describes the process and results of a FE analysis of the engagement of the Hawk T Mk2 aircraft into a Type A Barrier (BAN Mk2). The analysis was performed using RADIOSS, an advanced non-linear explicit Finite Element solver.

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.

The Application of Process Automation and Optimisation in the Rapid Development of New Passenger Vehicles at SAIC Motor
As a relatively young automotive company, SAIC Motor has drawn on the expertise of its UK Technical Centre to help in its objective to bring a new range of vehicles to market in an aggressive time frame. CAE has formed an integral part in doing this and the UK technical centre has worked closely with Altair Product Design amongst others to utilise its Engineers’ skills as well as the Hyperworks suite of software.

The paper aims to showcase what has been achieved to date, on the Roewe 550 medium car programme - currently on sale in China - and on another current vehicle programme, where processes have been developed further. Several interesting optimisation examples are highlighted in the development of the body structure as well as some key process improvement methodologies which have been jointly developed between SAIC and Altair to streamline the design process.

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.

Fast Tracking Rail Vehicle Design
Bombardier Transportation UK offers one of the most comprehensive and diverse rail vehicle portfolios in the world. The strategy is one of continuous development that provides the most effective and cost-efficient rail solutions for today and the future. A key ingredient is the use of Altair HyperWorks enterprise computer aided engineering (CAE) solution. Altair's technology is now present at every stage of the design process and has increased the efficiency of the product development process. The paper details how Altair tools have been used to generate Finite Element (FE) models of carbodies, bogies and secondary structures in reduced time scales. Significant weight and cost savings are achieved through structural optimisation of components such as large steel castings, aluminium extrusions and steel fabricated structures which are subjected to linear static, fatigue and abuse loading. Automated post processing facilitates the interpretation of results and the writing of detailed official reports.

Targeting Composite Wing Performance – Optimising the Composite Lay-Up Design
This paper shows how Altair OptiStruct, part of the HyperWorks suite, is used to provide a complete solution when designing with laminated composites, taking the design through concept stages to producing the final ply lay-up sequence. The technology is applied to the design of a laminated wing cover to produce a mass optimised design which meets the requested structural targets.
