摘　　要：采用流体力学基本原理分析和建立了电磁阀控挡位离合器的动力学模型,结合实验分析得到摩擦片摩擦系数特性曲线,通过直观的功率流向图描述出整个电磁阀控挡位离合器系统的功率传递;利用数学工具软件MATLAB仿真模块SIMULINK建立了仿真模型,以Ⅰ挡为例,得到电磁阀控挡位离合器的动态特性曲线和响应特性曲线,与实验测试结果对比,二者基本吻合,证实了动力学模型的正确性。采用功率流向图有助于分析电磁阀控挡位离合器系统的动力学特性。Dynamic model of solenoid valve control shift clutch that was established and analyzed using hydrodynamics theory and Friction coefficient of a couple of friction disks that was obtained in experiment were expressed;moreover terseness power-oriented graphs described system power transmission.First gear clutch Simulation model was set by using SIMULINK-toolbox,dynamic response characteristic and load-pressure characteristic were obtained and validated in experiment.It experiment also proved that dynamic model was exactitude.Using power-oriented graphs was propitious to research dynamic characters of solenoid valve control shift clutch.
