摘要： 在以往单柔性体系统振动研究和柔性多体系统动力学理论的基础上，对包含多个柔性体在内的机械系统振动响应进行分析。通过使用ANSYS和ADAMS软件建立以曲轴活塞机构为代表的系统动力学模型，然后使用柔性体代替机构中的不同部件进行振动响应比较计算的方法，得到系统中柔性体变化与系统整体振动响应变化之间的基本规律。这些规律能够为大型系统级振动分析模型的简化和计算精度保证提供必要的参考。

Abstract: On the base of vibration study of single-deformable-body system and the dynamic theory of multi- deformable-body system, vibration response of a mechanical system including multiple deformable bodies is analyzed. First of all, a crankshaft-piston mechanism is taken as a representation, and its dynamic model is created and analyzed by ANSYS and ADAMS codes. And then, the basic relations between the deformable-bodies and the system’s vibration response are obtained. These relations can provide a necessary reference for simplifying the vibration model of the large system and ensuring the precision of computation.

Key words: vibration and wave, system dynamic, virbrational response, ADAMS simulation, multiple-deformable-body
