摘要
分析了采用振型叠加法计算结构动态冲击响应的力学模型,在此基础上用有限元方法对某型车辆辅助变流器柜体进行了动态冲击仿真计算,运用IEC 61373标准对结构强度进行了校核。同时通过试验测试,对仿真计算的结果进行检验,验证了产品结构的可靠性和力学模型的正确性,为将仿真计算应用到产品前期开发提供了理论基础。
Mechanical model of dynamic shock response calculation using modal superposition was analyzed, and based on this mechanical model, a dynamic shock simulation calculation was conducted for auxiliary converter cabinet on a certain vehicle by means of finite element method, which was checked with application of IEC 61373 standard. Besides, results of simulation calculation were verified by means of experimental test. Reliability of the structure and accuracy of the mechanical model were assured with above calculation and test, which provided theoretical basis for the simulation calculation＇s application in product preliminary development period.
