同步器的优化设计和工作过程仿真

On optimization design and working process simulation of synchronizer

结合同步器的工作过程和同步器设计计算公式,以缩短同步时间为目的,选取了摩擦锥面的锥角α、结合齿的锁止角β、摩擦锥面的平均摩擦半径R、摩擦锥面工作宽度L四个对同步器性能影响较大的参数对同步器进行了优化。根据优化的结果在ADAMS里面搭建同步器的动力学模型,对同步器的工作过程进行了仿真。仿真结果体现出了同步器的锁止过程和同步过程,且优化后的同步时间与理论值误差小于3%。证明了该优化方法和仿真的可行性。

Combining the working process and design formula of synchronizer, for the purpose of shortening synchronization time, this paper selects four parameters which significantly influence the performance of synchronizer cone angle α,lockangle β, mean radius of friction cone R, and width of friction cone L for the optimal design. Based on the resuh of optimization, the paper further establishes a dynamic model in ADAMS and simulates the synchronizing process of synchronizer.The result demonstrates clearly the locking and synchronizing process of the synchronizer, and also shows that the error between the synchronizing time after optimization and the theoretical value is less than 3%, which proves the feasibility of the optimization method and the simulation.
