摘要

摘要: 解耦盘的运动使得解耦盘式液压悬置成为一典型的切换系统，它同时包含连续和离散两种动态，常规的建模方法都是采用集总参数模型或者液固耦合模型对液压悬置动力学特性进行仿真分析。在考虑液压悬置的混杂系统特征基础上，直接从切换系统理论出发，建立了解耦盘式液压悬置的切换系统模型，并采用逻辑判断方法制定了各模式间的切换策略，通过Simulink/Stateflow建立了切换系统仿真模型，该模型更能真实反映解耦盘式液压悬置的实际物理工作过程。最后进行了解耦盘式液压悬置动特性试验，验证所提出的切换系统模型的有效性。

Abstract: The hydraulic engine mount (HEM) with decoupler is a typical switch system for the movement of a decoupler and has two dynamical states: continuous and discrete. The conventional methods for the dynamic characteristics analysis of HEM with decoupler were based on the lumped parameter model or the fluid-structure interaction model. With the hybrid trait of HEM considered, the dynamic characteristics model of the switch system was established, and the switching strategy between different modes was proposed by logical judgment. By using Simulink/Stateflow, the simulation model of a multi-mode switchsystem was designed. The simulation model is accurate and can represent the actual switch system completely. The dynamic characteristic tests of HEM with decoupler were carried out, and the effectiveness of the proposed switch system model was verified by experimental results.
