中文摘要：

以某船用空压机系统为研究对象,建立系统的振动模型,进而推导出系统的振动微分方程.基于ADAMS软件建立了空压机系统的动力学模型,分析了该系统的振动特性,并与理论推导得到的系统固有频率及固有振型相比较,检验振动模型的正确性.分别对减振器的刚度和安装位置两个因素进行了仿真分析研究,结果表明：改变减振器的刚度和安放位置,可以降低空压机系统的振动.研究结果对空压机隔振系统的设计、减振器的选型和布置提供了一定的指导作用.

英文摘要：

Amarine air compressor system was taken as the research subject The vibration model of the system was built to deduce the differential equation. The virtual dynamics analysis model was also estabiishedto analyze the vibration characteristics of air compressor based on ADAMS software, comparing natural frequency and inherent vibration mode from the theory deduction to test the model. And simulation analysis of the stiffness and position of the shock absorberwere conducted by the ADAMS/Vibration. The results of simulation analysis indicate that it can decrease the vibration degree of the air compressor system by changing the stiffness and the position of the shock absorber. The research results provide certain guiding role for designing vibration isolation system of air compressor, selection and arrangement of the shock absorber.
