摘　　要：针对国内汽车空气干燥器自动化检测效率低、精度差的不足,依据国家汽车行业相关标准、结合厂家用户要求设计专用的在线检测系统。采用计算机控制理论与机电一体化技术、气动技术相结合,实现快速自动化在线检测。该系统可以完成干燥器的调压阀特性测试和密封性测试,并对测试数据自动分析处理、保存回放。试验表明,该检测系统能够高效准确地检测空气干燥器的性能,测试误差小于5%,测试不确定度小于0.5kPa,满足工业现场的要求。On the basis of correlative automobile industry standard and the requirements of manufacturer, this dedicated on - line detecting system is designed for the shortage of low degree automatic efficiency and detection precision of auto air dryer in the domestic. Fast automatic detection is achieved by using the method of combination of the technology of computer control, mechatronics and pneumatics. This system can detect the speciality performance of pressure regulating valve and seal of auto air dryer, in which online analyt- ical processing of test data is available, at the same time, saving and inquiring data is achieved. Through some experimental analysis, it is indicated that efficient and accurate detection of the performance of auto air dryer is realized, and the test errors are less than 5%, the test uncertainties are less than 0.5kPa, which can meet the requirements of operating industrial site.
