摘　　要：运用有限元数值模拟法研究了轿车车顶结构的模态特性、抗凹性能、覆雪强度、抗压强度等结构性能。系统评价了轿车车顶结构的静态、动态性能,包括载荷、边界条件的设置等,并给出了相应的评价准则及适用范围。将各个工况下的评价体系进行整合,得到合理的综合评价体系,为整车设计或车顶结构的相关产品研发提供了参考。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.
