Crash tests and numerical simulations are a vital source of information when designing safety elements for vehicles. To obtain homologation the vehicle's crash safety needs to be demonstrated. Based on three tests Euro NCAP program presents objective and comparable safety performances. Student Roadster is a prototype and will remain the only one built, therefore its adequacy has to be proven using a numerical simulation. The first stage of the simulation was a crash of the front bumper against an obstacle. The bumper is fixed on two dented beams that function as energy absorbers in the case of a crash. A 3D model has been built and discretized with finite element method in Catia while the simulation of the crash was done in Ls-Dyna. The results illustrate the importance of indentations in energy absorbent beams for plastic deformations form in those areas. Upgrading the front bumper model, crash test simulation for the entire vehicle SR is currently in the process.
