Research on Crashworthiness of Car Bumper System

Abstract:

The computer simulation method is used to study the crashworthiness of car bumper system. Firstly, the CAD model of the car and bumper system is established in CATIA. The pre-processing for the model is finished in Hyper-Mesh and the finite element model is established. Then the process of crash simulation is calculated in Pam-Crash. The simulation results are compared with the test results to verify the accuracy of the finite element model. Finally, the low-speed crash simulation of the bumper system is conducted. The crash displacement and deformation of the bumper system are forecast through the process of simulation, which can provide a reference for the next design and improvement.
