滚筒反力式制动检验台动、静态检定方式的比较

Comparison of dynamic and static verification methods of roller reaction brake test bench

对检定规程JJG 906-2015中静、动态制动力检定方法进行比较,分析静态和动态制动力检定方法在检定原理、方法、装置、数据计算、示值误差、不确定度来源及消除方法六个方面的不同。结合实际检定工作,得出动态检定法作为首次检定方法是滚筒反力式制动检验台检定工作的重要组成部分,是对静态制动力检定工作的重要补充的结论。

This paper compares the static and dynamic brake force verification methods in verification regulation JJG 906-2015,and analyzes the differences between static and dynamic methods in six aspects of verification principle,method,device,numerical calculation indicating the source of uncertainty ang its elimination method.Combined with the actual verification work,it is concluded that the dynamic verification method can be used as the first part of the actual verification work and is an important supplement to the static braking force verification work.
