摘要
设计一套基于PC控制的BMBS真空助力器性能检测在线装置,检测项目包括BMBS工作状态和非BMBS工作状态密封性、输入输出响应特性。运用伺服加载机构实现真空助力器加载速度的精确可调,提高在线检测效率;并且引用高速采集模式提高数据采样率。实验结果表明:该装置的密封性测量分辨率为0.01kPa,输入输出力分辨率为1 N,时间分辨率为0.01 s,可以快速、准确地进行BMBS真空助力器产品性能在线检测。
A set of online performance detection devices of the BMBS vacuum booster was designed based on PC control. Test items include vacuum sealing and input-output characteristic of the BMBS state and non-BMBS state. The servo-loading mechanism made load speed precise and adjustable to improve online test efficiency; the use of high-speed acquisition mode improved the data sampling rate. The experimental results show that vacuum resolution is 0.01 kPa, input and output force resolution is 1 N, temporal resolution is 0.01 s. It can detect performance of BMBS vacuum booster products online quickly and accurately.
