摘　　要：新设计的电机用气体冷却器需测试管束的固有频率。因此,在简化氢气冷却器结构的基础上,采用有限元法分析冷却器的模态参数,并采用"多点激励-多点响应"锤击法进行了模态测试。结果表明,有限元分析具有较好的准确性,冷却器管束固有频率满足相关要求。The nature frequency of the tubes of a new design gas cooler for electrical machinery should be tested.This paper uses Finite Element Method(FEM)to analysis the modal parameter of the hydrogen cooler,based on model simplification,and uses multi-excitation-multi-response hammering method to test the modal parameter.The results show that the result of the finite element modal analysis is available and the nature frequency of the tubes of the gas cooler meets relative ruler.
