摘要
离合器是汽车传动系统中重要的组成部分,其保证汽车平稳起步、使传动系换挡工作平稳的同时防止系统过载。膜片弹簧是膜片弹簧离合器中其重要的压紧元件,具有弯曲形状,起压紧摩擦副和分离机构作用,其设计的优劣直接影响汽车离合器的工作性能。采用ANSYS/LS-DYNA软件,进行了大端预加载荷后,模拟膜片弹簧小端加载的运动仿真,较真实地模拟了膜片弹簧离合器结合与分离时的应力变化情况,验证了该膜片弹簧满足设计的强度要求。
The clutch is the important part of the automobile transmission system, which ensures the ear start smoothly, makes the transmission shift smooth and prevents the overload of the system. The diaphragm spring is the important pressing element in the diaphragm spring clutch and it has a curved shape with the role of pressing friction pair and detaching mechanism. The design quality of diaphragm spring will directly influence the working performance of automobile clutch. The motion simulation of pin end loaded of the diaphragm spring is carried out based on ANSYS/LS- DYNA software, after preloading the diaphragm spring. The stress change situation about the combination and separation of diaphragm spring clutch is simulated, which confirms that the diaphragm spring can meet the design requirements of strength.
