基于能量法解耦的动力总成悬置系统优化设计

On Optimum Design of Powertrain Mounting System Based on Energy Decoupling

通过建立汽车动力总成悬置系统的动力学模型,进行了能量法解耦理论的推导,并将该方法应用到某客车动力总成悬置系统的改进中,结果表明,垂向和绕发动机曲轴转动方向的振动和其他自由度方向的振动基本实现解耦。

In this paper, by establishing the dynamic model of the powertrain mounting system, a theory of energy-based decoupling is derived. Then the theory is applied to tbe improvement of the powertrain mounting system of a bus. The results sbow tbat the vibration of vertical and rotation about crankshaft axle is basically deeoupled with that of the other directions.
