Performance improvement of car body structure in 100% frontal impact
Pages: 47-50
Year: Issue:  6
Journal: Engineering Sciences

Keyword:  100frontal impact simulation automotive structure optimization case test;
Abstract: <正>During the 100%front impact,all the parts of front car will participate in the course;the crash stiffness of bodywork will also reach the peak.During the crash,rational structure of bodywork can resist the distortion,absorb more energy and get better mode of distortion and low deceleration rate,so as to meet the performance of crash safety.The paper mainly makes optimization analysis based on the problems of front side rails,subframe,firewall,and optimization cases are confirmed which can decrease the intrusion and deceleration rate of the whole car.The structure of bodywork after optimization can meet the performance of crash safety.
