以实际工况下的测试数据为基础,建立了简化的车内振动传递路径分析模型。在此基础上,以发动机悬置刚度为设计变量,综合考虑悬置系统能量解耦和车内振动,建立了基于灰色粒子群优化算法的多目标优化模型。并以某型卡车为例,进行了多目标优化求解。实验和优化结果表明,在得到较好能量解耦的同时,降低了车内振动,实现了能量解耦和车内低振动的优化匹配。

Simplified vehicle vibration TPA model was established based on the actual transfer path test datum.On the basis of that,multi-objective optimization model of powertrain mount system was established based on GPSO algorithm with considering energy decoupling and vehicle vibration, mounting stiffness parameters were taken as design variables.Taking a truck for example,a multi-ob-jective optimization solution was conducted.The test and optimization results show that the optimiza-tion method can get better energy decoupling and lower vehicle vibration,while achieving the optimal matching of energy decoupling and cars and low vibration.
