摘　　要：目前用于发动机液力悬置系统建模的常用方法是解振动微分方程和列流体平衡关系式 ,本文针对惯性通道 -解耦式液力悬置 ,提出应用键合图理论进行系统建模和仿真分析。同时对两种常用方法的不足加以改进 ,并着重从系统结构的简化、力学模型和数学模型的建立过程、仿真结果与实验结果的对比等方面对这三种建模方法加以分析比较 ,讨论了键合图方法与其他建模方法各自的特点及其适用范围。In this paper, three modeling methods of the hydraulic engine mount with inertia track and decoupler are discussed, and their physical models and mechanical models are presented. Two of the three above modeling methods are changed according to the model introduced in many papers, and the rest is the bond graph method.In the last part of the paper, their modeling process and dynamic simulation between these methods are mainly discussed.
