摘　　要：由于汽车的振动激励源中,汽车动力总成是一个明显的主要方面,故而对于乘客的乘坐舒适性而言,必然会有较大的影响作用。所以合理的设计对于汽车动力总成悬置系统来说至关重要。文章以某客车实际模型的质量、几何等参数为依据,建立了多刚体动力学模型,并且在建立模型的过程中,采用的软件是ADAMS/view和ADAMS/vibration,此后更是对所建立的动力总成及其悬置系统进行了相关的固有特性分析。接着,设计变量选为悬置的刚度以及安装角度,并将能量解耦方法以及撞击中心定理应用其中为前提,而且将目标函数选为在两个主要振动方向上的能量解耦率达最大,以进行优化设计。优化前后做性能对比显示,优化后悬置系统隔振性能有所改善。In order to improve the riding comfort of the automobile and increase service life of the engine and other components by signifi cantly suppressing the vibration,proper design of powerplant mounting system play a decisive role.Based on the mass,geometry and other parameters of the actual model of a bus,this thesis builds the rigid dynamic model by using software ADAMS/View&ADAMS/Vibration.Based on the model,the inherent characteristics are simulated and analyzed in the mounting system.In addition,the decoupling design of the mounting system is also carried out.On the basis of establishing the parametric model of the mounting system,the stiffness&the fixing Angle of mounts is chosen to be design variable.Then the energy uncoupling rate of two principal directions of vibration is chose to be target of mount design.By using Center of percussion Theorem&the method of energy decoupling,the performance comparison before and after optimization shows that the vibration isolation performance of the suspension system is improved after optimization.
