| 摘 要： | 以某燃料电池车为研究对象,建立了电机动力总成悬置系统的动力学模型,通过分析动力总成悬置系统的耦合特性和加速工况时的瞬态振动,指出了原始设计不合理的地方.在此基础上,以悬置位置与悬置刚度为设计变量,以加速工况悬置处的瞬态动反力为目标函数.运用遗传算法对动力总成悬置系统进行了优化设计,从而有效地改善了动力总成悬置系统的隔振性能.

| Abstract: | Taking certain fuel cell vehicle as the target of study,the dynamics model of the electric motor motivity assembly suspension system was established.By means of analyzing the coupling characteristics of motivity assembly suspension system and the transient state vibration during the working condition of acceleration,the unreasonable places of the original design had been pointed out.On that basis,taking the suspension position and the suspension rigidity as the designing variables,and the transient stated d... |
