Car Crash Test, Trajectory Calculation, Simulation BenchmarkingAbstract
Car crash tests are universally acknowledged for their critical role in assessing the passive safety performance of vehicles, given their straightforward and compelling evidence. Despite their effectiveness, traditional physical crash tests are notorious for their lengthy setup times and high costs. The evolution of Finite Element Analysis (FEA) technology, complemented by the improved precision of FEA dummies, has paved the way for evaluating passive safety through computational simulations. In the domain of virtual testing, benchmarking is essential for validating the accuracy of simulation outcomes. Among the pivotal benchmarking metrics, the congruence of dummy limb and head trajectories emerges as a dependable measure of the FEA model’s accuracy. This alignment is especially significant, as the head is recognized as one of the most vulnerable areas during a crash.
