Structure Improvement and Experiment Validation for a Car Side Impact


Article Preview

A side impact simulation model for a car was built according to China New Car Assessment Programme(CNCAP) and the 120ms response of the side impact was calculated by Pam-Crash software. The side security performance of base model was evaluated with the assessment criteria for the side security which was defined base on the experience and development requirement. Because of the stiffness insufficiency of base model, the body side structure was improved by multiple optimizations to improve the side security performance of body-in-white. The optimal scheme was validated by the test results, and the side security performance satisfies the production development requirements. The reliability and accuracy of the side impact model were validated according to the comparison analysis of test and simulation.
