离合器是机械传动中常用的部件，位于发动机和变速箱的飞轮壳内，可将传动系统随时分离或接合，切断和传递发动机输出的动力。利用matlabSimulink建立离合器接合/分离模型，可对离合器工作原理进行仿真。(Clutch is a commonly used component in mechanical transmission, which is located in the flywheel housing of engine and gearbox. The transmission system can be separated or joined at any time, and the power of engine output is cut off and transmitted)
