Abstract: The crashworthiness of a passenger car is very important to the safety of the driver and the passengers in the car when the car is involved in an accident, thus it is of great interest to enhance research work on crashworthiness analysis of the car. Computer simulation techniques is applied to study the crashworthiness of a complete passenger car under development. Simulation results are compared with experimental ones and used to guide modification of the frontal structure for improvement of crashworthiness characteristics. Satisfactory results are obtained via optimization of a few key components.

Key words: Safety improvement, Vehicle crash Computer simulation
