【摘要】 动力总成悬置系统是汽车振动系统的一个重要子系统,对改善汽车平顺性和舒适性有很大的影响。为了能够提高动力总成橡胶悬置系统的性能,该文针对某国产轿车的橡胶悬置系统,应用机械系统动力学仿真分析软件ADAMS,建立了动力总成橡胶悬置系统六自由度的动力学模型。通过对动力总成橡胶悬置系统在不同工况下的自振频率、振型、系统的能量分布、各悬置元件的平动位移和角位移的计算及分析比较,尤其将悬置元件的平动位移和角位移作为重点比较对象,讨论了悬置元件的安装角度和刚度系数对上述性能参数的影响,并得出了动力总成悬置系统的最佳方案。更多还原

【Abstract】 Powertrain mount system is a very important subsystem in the automobile vibration system,it has a large influence on the smoothness and amenity of the automobile.In order to advance the capacity of powertrain mount system,the software ADAMS is used to set a six-degree-of-freedom dynamic model of rubber powertrain mount system.By calculating and comparing the normal frequency,vibration mode,the distribution of the energy,the displacement and angle displacement of the mounts in the powertrain rubber mount system,especially,focusing on the displacement and angle displacement of the mounts,we discuss the effects which are produced by the fixed angle and stiffness coefficient on the above mentioned performance parameters,then choose the best mount system.更多还原
