2018 MATHMOD - A Vehicle Model for Crash Stage Simulation

Simulation of vehicle impact stages is gaining more importance as the years go by. The reasons are an increase in the requested vehicles performances in terms of passive and active safety but also the
necessity to investigate causes which lead to car accidents. The paper describes a special purpose 2D vehicle model for time-efficient crash stage simulation and therefore introduces the equations which rule
over the model first. The Finite Element Method (FEM) represents the basis for the problem’s analytical formulation. However, the various vehicle areas’ different stiffness involves its estimation using real
vehicle-to-barrier crash tests as a reference (carried out by EuroNCAP, NHTSA, etc.). Based on the obtained stiffness value, performed simulations demonstrate the applicability of the method to the vehicleto-vehicle impacts contained in databases like AREC, VERSUE, etc. Furthermore, real-world crashes and results of the developed model’s simulations are compared for four different exemplary cases, highlighting the possibility to fully describe the events’ dynamics and the vehicles deformations. Therefore, the described model simulation times are evidently shortened in respect to more complicated solution
approaches, like FEM or Multi-Body models. These resources savings also imply the possibility to simulate activation of Advanced Driving Assistance Systems (ADAS), i.e. the simulation of multiple impact
configurations as the ADAS features vary.
