缩堵孔径等对单车试验器机能试验的影响分析

摘要

The degree of effect of the fixed reducing and plugging aperture errors of the single-car tester and the environment temperature change on the functional test, as well as troubles in operation of the single-car tester with the reducing and plugging aperture + switch type electromagnetic valve mode is analyzed. The advantages of the single-car tester with the mode of high-frequency switch type electromagnetic valve controlled by duty ratio signal are described.%分析了单车试验器缩堵固定孔径误差、环境温度变化对机能试验的影响程度,以及缩堵孔径十开关型电磁阀模式的单车试验嚣使用过程中存在的问题,介绍了占空比信号控制高频开关电磁阀模式的单车试验器的优点.
