摘　　要：通过对汽车制动试验台传统检定方法的研究,设计了设备检定系统,完成了制动试验台的静态、动态和在线检定,实现了自动化检定。由于现场干扰多、误差较大,系统采用了数字滤波法对检定数据进行处理。通过研究检定数据的特点,选用了未确知有理数滤波算法,有效地提高了检定的准确度,实现精确检定。In this paper,traditional verification methods for auto braking test machines were studied.On this basis,a new system that can realize static,dynamic and online auto-verification was designed.Because there is much noise,which causes larger error in the working field,a digital data-filtering method was used to process the verification data.By studying the characteristic of the data,the unascertained rational number filtering method was eventually selected,which can improve the verification accuracy effective...
