摘　　要：发动机悬置系统设计中,可以通过刚度值、布置位置的调整来适应不同动力总成的性能需求。但在实际车型开发中,由于机舱布局延续性、不同动力总成悬置通用化需求,给予悬置系统的调整空间往往是有限的。在不能对悬置布置位置、悬置软垫结构进行大的变更前提下,考虑左悬置软垫采用双主簧结构,实现最优化的三向刚度比,并适应各种动力总成越来越高的NVH性能需求。In the design of engine mounting system,the stiffness value and arrangement position can be adjusted to meet the performance requirements of different power assemblies.However,in the actual development of vehicle models,due to the continuity of engine room layout and the need for generalization of different powertrain mounts,the adjustment space for the mounting system is often limited.On the premise that the mount arrangement position and the mount cushion structure cannot be greatly changed,the left mount cushion is considered to adopt a double main spring structure to realize the optimized three-way stiffness ratio and adapt to the increasingly higher NVH performance requirements of various power assemblies.
