我们常用的百分表的量程只有一厘米。故路面回弹弯沉测定时,几乎在每个测点都要调整表架的高度,较费时间。于是,我们想到采用大量程百分表。这样,我们就可以减少调整表架的次数,节省测试的时间。但采用大量程百分表时,如仍按传统方法读数,则百分表上的读数就较大,常为四位数字。这时,读数、记录、计算,都要增加麻烦。即使常用的百分表,按传统方法,其读数多为三位数字,也不方便。下面介绍一种新的读数方法。除路面严重损坏的情况外,路而回弹弯沉的数 Our commonly used dial gauge range of only one centimeter. Therefore, the determination of the road surface rebound deflection, almost every measurement point to adjust the height of the table frame, more time-consuming. So, we think of using a large scale dial indicator. In this way, we can reduce the number of adjustment table shelf, save test time. However, when using large-scale dial indicator, if still according to the traditional method of reading, then the reading on the dial indicator is larger, often four digits. At this time, readings, records, calculations, should increase the trouble. Even the most commonly used dial indicator, according to the traditional method, the reading of more than three figures, it is not convenient. Here’s a new reading method. In addition to serious damage to the road surface, the road and rebound deflection number
