摘要
本文分析了发动机激振力状况,建立了悬置系统的自由振动模型,并采用测试技术和频谱分析方法研究了悬置系统的隔振性能。通过分析实际的AY660H型大客车发动机悬置系统的振动状况,得出了一些有实用价值的结论,说明了这种分析发动机悬置系统的方法是可行的和实用的。
In this paper, the engine excitation force is analysed and the free vibrationmodel is established for an engine suspension system, of which the vibrationisolation performance is studied with the technique of measurement and testas well as the spectrum analysis method. Some conclusions of practical valueare obtained by applying these methods to the AY660H Coach. This analysismethod of the engine suspension system is proved to be reasonable andpracticable.
