本文综合分析了高速激光弯沉检测设备HSD的工作原理和实现方法,对不同行车速度下HSD测量数据,以及HSD与FWD测量数据进行了对比,得到如下结论:行车速度越高,HSD测得的弯沉值越小;HSD重复测量数据具有较好的稳定性;HSD与FWD检测结果的相关性较好。 This paper analyzes the working principle and realization method of high speed laser deflection detection equipment HSD, HSD measurement data under different driving speeds, as well as HSD and FWD measurement data were compared, the following conclusions: The higher the driving speed, HSD measured The smaller the deflection value; the better the stability of the HSD repeated measurement data; the better correlation between the HSD and the FWD test results.
