Title Multi-body Dynamics Simulation For The Diaphragm Spring Clutch And Its Control Configuration
Abstract
In this paper, a diaphragm spring clutch and its operating system model is established, and then we analysis the entire system with the theory of the multi-body system dynamics. In order to simplify the simulation, we discuss the way that the diaphragm spring of the model will be pided into several parts along the circumferential direction, and then the every part of the diaphragm spring will be flexibly connected with each other in order to avoid the more complex rigid-flexible multi-body system dynamics simulation analysis. Through the analysis of the relationship between the large end and the small end deformation of the the diaphragm ring, we put out the simulation curve chart of them. Finally, the final result is gained by comparing the analysis result of reality and ADAMS simulation which matches each other very well. The model approximately reflect the dynamics of the diaphragm ring clutch and its operating system, which has a certain significance for the preliminary simulation of the actual system.

1.1 引言
离合器是汽车传动系中重要的组成部件，对于汽车的动力性、燃油经济性和舒适性等性能有很大影响。离合器是汽车传动系统中直接与发动机相关联的部件，主动部分和从动部分可以暂时分离，又可以逐渐接合，并且在传动过程中还有可能相对转动，通过主动、从动两部分的相互作用把发动机的动力扭矩传递给驱动系统，来实现汽车的平稳起步、换挡平顺以及防止传动系统过载等功能。离合器操纵系统是驾驶员借以使离合器分离，而后又使之柔和接合的一套系统。它始于离合器踏板，终止于飞轮壳内的分离轴承。
