用试验模态分析技术确定了 CZ480柴油机的机体各阶振动频率 ,用 STAR5 .0试验模态分析软件对机体在各阶振动频率下的变形进行了分析 ,为机体有限元模型的合理性提供了试验依据 ,为了解该机体的动态特性和改进设计提供了理论基础。
The experimental modal analysis technique was used to determine the vibration frequencies of CZ480 diesel engines. The deformation of the CZ480 diesel engine was analyzed by STAR5 .0 modal analysis software at various vibration frequencies to provide the rationality of the finite element model Experimental basis, in order to understand the dynamic characteristics of the body and improve the design provides a theoretical basis.
