Design and Implementation of High-precision Measurement System for High-speed Rail Wheelsets
Aiming at the problems of backward measurement means,low precision,low efficiency and automation level of wheel set dimension measurement in China,a contact type automatic measurement system for wheel set dimensions is designed and implemented.The system realizes the automatic measurement of wheel set's shape dimension by using contact trigger probe and displacement sensor.Through relative measurement principle and temperature compensation algorithm,it can measure the length and radial dimension of wheel set including inner distance,wheel position,journal diameter,etc.Through the practical experiment and trial verification in the production and assembly site of high-speed rail wheel set,the measurement results of the system have high precision and high consistency,and meet the requirements of measurement accuracy of each dimension of high-speed rail wheel set.
