Enabling EV Excellence – Simulation Helps Rimac Improve Structural Design of Innovative Hypercar
Rimac Automobili’s main challenge has been to design a monocoque as a single carbon fiber part with an unprecedented size. Hence, in the development of the monocoque, the main topic to manage was the material, a lightweight, carbon fiber reinforced with epoxy resin. As this carbon fiber is an orthotropic and brittle material, its representation in a finite element (FE) material card is very difficult. To meet this challenge the company introduced Altair HyperWorks™ into their development process.

MDGo
Statistics on fatal vehicle accidents show that victims most often do not die during or right after a crash, but in the hours and days afterwards, with research indicating that up to 44 percent of people who died in car crashes could possibly have been saved if first responders and hospitals had
real-time, detailed information about the victim’s injuries. In an effort to transform data received from the car sensors into meaningful information about the victim's injuries, the MDGo team began applying crash simulation using Altair Radioss™. The Altair Startup program was a major help to the Israeli startup company in creating a system which automatically alerts first responders and hospitals of accidents, and reports on potential injuries.

Addressing Design Development Challenges Through Simulation Driven Platform
Automotive suppliers are facing many challenges in having in-house simulation capabilities compared to that of OEM’s. One of the ways to overcome these challenges is to invest in simulation technologies that require an affordable initial investment, the ownership cost of which is low, the codes are reliable & proven, and the suite of tools provide suppliers access to a broad range of solvers (a true multi-physics environment) helping them pick and choose the solvers as per their simulation requirements. In the early stage of in-house simulation implementation at Endurance Technologies, HyperWorks was being adopted primarily for pre and post processing due to its extraordinary FE modeling solutions. With constant support, Altair team has helped Endurance in exploring and implementing various HyperWorks solvers at Endurance Technologies.

Optimal Design Exploration Using Global Response Surface Method: Rail Crush
As design exploration and optimization methods have become commonly accepted across a range of industries, such as aerospace, automotive or oil and gas, they are frequently utilized as standard practice to efficiently produce designs and aid critical engineering decisions. The widespread acceptance of these methods coupled with the power of modern computing has led to applications across a range of design problems and ever-increasing complexity. The size and scope of this expansion continually pushes the boundaries of existing exploration and optimization methods. Furthermore, a complete exploration of the optimal design space includes computationally intensive features such as multi-objective optimization, to understand the trade-off between competing objectives, and global optimization, to avoid local extrema.

NASA
A Safer Landing with Water Impact Analysis



Using Altair’s own HyperWorks virtual simulation suite, Altair ProductDesign built an accurate finite element model of the module from CAD data supplied by NASA, as well as a section of water and air which matched the conditions from the lake used during the physical tests. The effect on the module’s structure during impact was simulated to gauge how well the results correlated with the physical tests. The results showed excellent correlation between the simulation and physical tests, identifying areas where the model, input parameters and meshing methods could be improved to give a more accurate prediction of the event.
