摘　　要：为了研究某变速箱同步器的换挡性能,结合同步器耐久试验台的换挡控制和试验规范,采用SimulationX软件集成ADAMS、ABAQUS和CATIA构建了同步器模型、换挡控制机构模型、换挡机器人模型,对同步器的一挡进二挡和二挡进一挡两种换挡工况进行了仿真分析,得到了换挡力、输入轴转速和换挡位移等参数,并且与台架试验数据进行了对比,分析结果表明,两者参数曲线基本一致,区别在于仿真换挡时间较台架试验时间稍微提前,由此验证了仿真结果的可行性和准确性。In order to research the shiftability of a transmission synchronizer, the synchronizer model, shifting control mechanism model and shifting robot model are built by adopting Simulation X integrated AD- AMS, ABAQUS and CATIA based on shifting control and test specification of synchronous durability test bench, two kinds of shifting process conditions of 1 - 2 upshift and 2 - 1 downshift are simulated, so the shifting force, shifting displacement and input shaft speed are obtained. The simulation data are compared with test data, the analysis results show that they are basically identical, the difference is that the simulation shifting time is slight- ly ahead of the bench test time, the feasibility and accuracy of simulation results are verified.
