| Abstract: | In this paper,the general property of vehicle roof structure,including modal characteristic,dent resistance,strength of roof-snow and roof crush are studied with finite element simulation.Static and dynamic property of car roof structure,including load and boundary condition setting are evaluated,and corresponding evaluation criteria and scope of application are given.Finally,the evaluation system comprising various conditions is integrated,and a reasonable comprehensive evaluation system is obtained.This system provides a significant reference for the design of vehicle and roof structural optimization and improvement. |
