摘要

摘要: 为了研究大功率自动同步离合器棘轮棘爪之间的碰撞特性，以4.5 MW自动同步离合器的核心部件棘轮棘爪机构为对象，利用RECURDYN软件建立了棘轮棘爪的动力学仿真分析模型，结合碰撞问题一般求解方法，对棘轮棘爪碰撞啮合过程进行了仿真分析。研究了棘轮棘爪差动角速度、接触刚度系数等对碰撞力和棘轮速度的影响，获取了棘轮棘爪之间的碰撞特性。

Abstract: In order to analyze the characteristics of collision between ratchet and pawl of a synchronous-self-shifting clutch, this paper studies the core component of ratchet and pawl of the 4.5MW synchronous-self-shifting clutch and uses the RECURDYN software to build the ratchet and pawl simulation analysis model, which is based on a general contact problem solution. The ratchet and pawl collision process is simulated and analyzed. The influences of the differential angular speed of the ratchet and pawl and the contact stiffness coefficient on the impact force of the ratchet and its speed are studied, thus obtaining the collision characteristics of the ratchet and pawl.
