| 摘 要： | 本文应用复合三线摆法测得了某轿车动力总成的相关参数，对动力总成的激振源进行了分析。在ADAMS下建立了动力总成悬置系统的动力学仿真模型，对悬置系统进行了模态分析，结果表明该系统存在耦合现象，阻尼相比刚度对悬置系统影响较小；对怠速工况下悬置元件上受力和位移情况进行时域和频域分析，发现该悬置系统中前悬置是主要的振动传递路径；解释了曲线波动原因，指出Z向是振动控制的主要方向，Z向存在变形位移不一致，说明悬置系统在作Z方向的自由振动的同时，还在参与绕X和Y方向的角振动，指出下一步改进设计中，应该降低系统振动的耦合程度。

| Abstract: | The paper measures parameters of power train on certain car through a complex three-line pendulum,and analyzes the excitation source of power train.A stimulation dynamic model of power-train mount system is made on ADAMS to do analysis.The results show that the coupling exists in the system and damping has less effect on the suspension system,while compared to the stiffness.Analysis on stress and displacement to suspending parts has been carried out during some period and frequently at idle speed,which indi... |
