Measurement Work Exploring the Substitute Scheme for Gyroscope Trajectory Method in Measuring the Track Regularity

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.
