摘　　要：以某前置前驱四缸四冲程横置发动机悬置系统为研究对象,利用Maxwell模型对橡胶悬置和液压悬置进行动力学参数化并实现其频变特性,在MSC Adams/view中建立悬置系统动力学分析模型与整车刚柔耦合动力学模型.通过模态解耦优化,提高动力总成悬置系统主要激励方向的模态解耦程度.在含Maxwell模型的悬置系统和整车上的计算结果表明,悬置系统的隔振性能显著提高.A mounting system for a powerplant with a four-cylinder, four-stroke engine is studied, the frequency dependency characteristics of rubber mount and h · ro mount are realized with Maxwell model. An engine-mount system and an entire vehicle kinetic model are set up Pin MSC Adams/view. Through modal decoupling method, the coupling characteristic of the engine-mount system is improved. The results on engine - mount system and entire vehicle indicate the vibrating isolation performance of the mounts are improved significantly after the optimization design.
