【摘要】为分析某一型号轿车发动机液阻悬置在低频的动态特性,建立该悬置集总参数模型,应用MATLAB软件仿真的动特性曲线与试验曲线基本吻合,表明所建立的液阻悬置模型能较精确分析该悬置的动特性；并应用ADAMS/CAR软件建立整车模型,通过整车仿真来比较液阻悬置和橡胶悬置的隔振性能,结果表明前者具有更好的隔振性能.%A lumped parameter model of a hydraulic engine mount (HEM ) is built in order to analyze the low-frequency dynamic responses of the engine of a car. MATLAB code is used and the experiment is done for dynamic characteristics analysis. Both results are mutually in a good agreement. It shows that the HEM model can be used to analyze the dynamic response of the engine mount precisely. The full-vehicle dynamic model is built by ADAMS/CAR. Numerical simulations of the full-vehicle's dynamic performance are carried out for the HEM and the rubber mount respectively. And their vibration isolation performances are compared mutually. The results show that the former have a better vibration isolation performance than the latter. 【总页数】4页(127-130)
