摘　　要：分析了汽车行驶工况,根据汽车发动机的瞬态工况计算出机械式手动变速器的动态载荷,以此设计出加载试验台控制系统。试验台利用工业PC进行现场数据采集,监视系统运行状态,通过CT-NET总线实现工业PC与CT变频器之间的通讯,CT变频器软PLC进行电机实时控制,模拟动态载荷并实时加载。This paper analyzes vehicle driving cycles, works out dynamic load of automobile manual transmission based on the real time driving cycles of the vehicle engine, and designs the control system of beneh. The bench uses IPC to acquire the data, and monitors the running state of the bench. Communication between IPC and CT variable-frequency is achieved by CT-NET bus, soft PLC of CT variable-frequency drive is used to motor online control, and offer real time load by using dynamic load.
