摘　　要：文章以搭建换挡杆耐久试验台为目标,建立了一整套基于位置触发的闭环控制系统。通过LabVIEW软件建立控制策略,对通过NI数字采集卡USB-6251实时采集到的光电开关电压信号进行处理,实现不同控制目标下的命令输出,采用Modbus协议输出控制伺服电机正反转。试验台的设计思路不仅可以满足换挡杆一个试验要求,也为汽车类似零部件试验台搭建提供了参考。In order to buiht the durability test bench for testing shift lever, a complete position closed-lnop control system is created. The control strategy is established with LabVIEW, the digital card USB-6251 is utilized to capture the real-time signal of photoelectric switch, realizing the command output in the cases of different control targets, and the servo motor is controlled through the Modbus protocol by the LabVlEW software until the target is achieved. It＇s proven that the design coneept is not only helpful to achieve the test requirement of shift level＇, but it provides the reference for the similar components in building test bench.
