摘　　要：为了制定变速系统的较优换挡策略,研究了不同同步力作用时换挡参数对换挡同步过程的影响,介绍了试验台架的结构组成及其实现的功能,简化了锁环式同步器同步过程模型,建立了验证同步器使用寿命的数学模型,完成了相关的性能仿真研究与试验研究。研究表明,针对不同换挡参数选择合适的同步力,不仅可以满足换挡品质和同步器使用寿命的要求,而且能降低同步过程中的能量损耗,同时为制定合理的换挡控制策略MAP图奠定了基础。In order to formulate the optimum shift strategy, the shift synchronization process af- fected by shift parameters is studied when the synchronization force is different values. The structure and function of the test bench is introduced. And then, the synchronization process models are simpli- fied and the model of service life of the lock ring synchronizer is given. The simulations and experi- ments of synchronizing process equipped with different ble synchronization force is completed. The results of shift parameters which are loaded by the varia- the study shows, the appropriate synchroniza- tion force for each shift parameter can not only meet the requirements of the shift quality and the serv- ice life of synchronizer, but also reduce the energy loss of the actuators during the synchronization process. And the suitable MAP for shift control strategy can be established in the future.
