摘要
柴油机机体是柴油机的主体结构部件，研究其动态特性对于了解整机的振动特性非常重要。本文介绍了柴油机机体的试验模态分析方法，以及用该方法分析了６１０８型柴油机机体。求得该机体的前八阶模态频率、阻尼及振型。
The method of experimental modal analysis for diesel engine cylinder block is introduced and applied to a Yc6108 diesel engine. The first eight modal frequencies and damping parameters are obtained, which may serve as the basis of structure optimizing for the system.
