摘要
指出在轨道平顺性测量中轨道检查仪关键器件陀螺仪存在的局限性,通过理论验证,提出一种新的替代方法,即采用传统的长度测量传感器对转角进行测量。通过理论推导,给出新方法的测角数学模型,同时分析了不同基本弦长下其应用的相关问题,以拓展解决此类问题的思路。
The author points out the shortage of the gyroscope which is one of the key parts in the railway track inspection device during the measurement of track regularity. And after theoretical verification, a new method is put forward to replace it, i.e., the new method is carried through traditional length measurement sensor used to measure the angle of rotation. By theoretical deduction, the author gives a mathematical model for measuring the angle corresponding with the new method, meanwhile, the author analyzes the relevant application problems under different chord length, in order to widen the thoughts of solving this kind of problems.
