摘　　要：重型汽车是机械自动变速器(automatic mechanical transmission,AMT)合适的应用对象。台架试验是AMT研究开发的重要环节。通过台架试验,进行AMT性能测试和分析,优化发动机和传动系统的匹配参数及控制策略,为AMT的装车应用奠定基础。针对所开发的AMT样机,在分析重型汽车AMT台架试验的功能需求基础上,提出了试验台测控系统方案,分析了数据采集及通信的方法;分析了AMT执行机构的特点,提出了执行机构的控制方法,在Delphi软件平台基础上开发了AMT试验台试验测控软件,使试验系统具备了先进的试验功能。Automatic mechanical transmissions （AMT） are suitable for use in heavy duty vehicles. Bench testing is an important task of the research and development. Many objectives, such as AMT performance testing, matching AMTs with engines, and optimizing control rules, can be achieved through bench testing, thereby laying a foundation for AMT application. An AMT testing bench is built up based on a developed AMT. By analyzing the performance requirements of AMT bench testing for heavy duty vehicles, a testing-controlling system scheme is proposed and methods of data acquisition and communication are analyzed. Control methods for actuators are proposed based on analyzing the characteristics of AMT actuators. A testing-control program for AMT bench testing is developed based on the Delphi platform. The entire bench testing system possesses advances test functions.
