摘要
概述了动态分析的基本方法即模态分析和受迫响应的基本原理，并以此对482Q柴油机机体进行了试验模态分析和受迫响应分析，在此基础上找出了该机体的薄弱部位并对其进行了改进设计，大大提高了该机体的动态性能。
This paper has summerized the basic methods of dynamic analy-sis,such as the principle of the modal analysis and the forced response simulation. By applying the methods, the experimental modal analysis and the calculation of the forced response simulation have been carried out on Model 482Qdiesel enging cylinder block. The weak sections of the cylinder block have beendetermined according to the result of above analysis and the improvement in design has been made which produces a much better dynamic characteristics of thecylinder block.
