摘要

摘要: 基于多目标优化理论,建立了一种发动机悬置系统优化设计模型,通过悬置刚度和位置参数的合理设置保证了主要振动方向上的能量解耦率最大化。分别以发动机悬置系统垂直方向和绕曲轴方向的能量解耦率最大为优化目标,以悬置刚度参数和位置参数为优化设计变量,考虑固有频率和动力总成参数的约束,构造了悬置系统六自由度模型,并利用非支配排序遗传算法对该系统进行多目标优化。最后该方法被应用于某型汽车发动机的悬置系统设计。

Abstract: An engine mounting system optimization model was established based on the multi-objective optimization theory, and the maximum energy decoupling rate of main vibration directions had been obtained by reasonable setting of mounting stiffness and position parameters. A 6-DOF model for mounting system was constructed with the maximization of energy decoupling rate of vertical and crankshaft rotation directions as optimization objectives, electing the mounting stiffness parameters and position parameters as optimization design variables. Taking into account of constraints of the natural frequency and engine mounting system parameters and using non-dominated sorting genetic algorithm, a multi-objective optimization was conducted to this system. Finally, the present method was applied to a practical vehicle engine mounting system.
