Apply accurate and effective simulation techniques to design safer vehicles

Occupant Safety Simulation

Occupant and pedestrian safety are critical design aspects. These aspects determine whether a vehicle can be homologated. Therefore thorough prototype testing needs to be done before a vehicle can go to market. However, this testing is expensive and can cause significant delays, especially when problems are discovered. For this reason, vehicle manufacturers try to save prototyping time and cost by doing upfront research and analysis using simulation.

Yet occupant safety simulations can be computationally intensive, especially for long-duration events. With the advent of driverless vehicles, new seating positions and restraints systems are on the increase; compliance in terms of population gender, age, and size is becoming more critical. As a result, the number of relevant testing scenarios (or load cases) keeps on increasing. Therefore engineers need to carefully balance between accuracy, model size and calculation time. They need solutions where they can pick the right method for their problems. When using Simcenter Madymo, engineers can apply a variety of simulation techniques, and find a set of validated crash dummy models and human body models in a database. Simcenter Madymo uniquely combines the capabilities of multibody (MB), finite element (FE), and computational fluid dynamics (CFD) in a single CAE solver. This will allow engineers to do all their calculations at a scale that fits the application.
