发动机悬置系统刚度的研究

The Research of the Engine Mounting Stiffness System

通过研究发现,发动机悬置系统对车辆的NVH表现影响比较大,文章通过调整整车悬置长度、悬置强度、正时罩盖(又称发动机前罩盖、正时链条盖)强度、悬置螺栓安装点等结构参数,对悬置系统进行仿真计算,提高发动机悬置系统的刚度,优化发动机NVH性能,减轻产品的重量,从而达到最优化设计。

Based on the investigation,the engine mount system has a greater effect on the NVH characteristics.In this paper,by adjusting the vehicle mount length,mount strength,timing cover(also know as the Front Cover,Timing chain cover)strength,mount bolt installation point and other structural parameters,simulating calculate the engine mount system,improve the stiffness of the engine mount system,optimize the engine NVH,reduce the weight of the product,so as to achieve the optimal design.
