摘　　要：为研究汽车爆胎应急安全装置的安全问题,构建爆胎应急安全装置和汽车轮毂有限元模型,通过对爆胎应急安全装置和轮毂的有限元力学分析和模态分析,确定装置应力分布及危险部位,并对危险部位进行结构优化.结果表明:爆胎应急安全装置的危险部位为螺栓连接端部,优化后危险部位最大应力降低了23.9%,且与外界激励不会产生共振问题,满足安全使用要求,为爆胎应急安全装置的设计提供了理论参考.In order to study the safety problems of the emergency safety device for automobile tire burst,the finite element model of the emergency safety device and the wheel hub of the automobile is constructed.Through the finite element mechanical analysis and modal analysis of tire burst emergency safety device and the wheel hub,the stress distribution and the dangerous parts of the device are determined,and the structure of the dangerous parts is optimized.The results show that the dangerous part of the tire burst emergency safety device occurs at the end of the bolted connection,the maximum stress of the dangerous part is reduced by 23.9% after optimization,and there is no resonance problem with external excitation,which meets the requirements of safe operation,and provides a theoretical reference for the design of the tire burst emergency safety device.
