Using high-precision and high-speed continuous measurement of wheelsets is an important technique for high-speed railway joint debugging, safety assessment, wheel-rail relationship and system dynamics simulation research. This paper systematically discusses the basic principles of high-speed wheelset and the design method based on the integrated error minimization, the manufacturing technology based on reliability, the precision-based dynamic and static calibration and other key technologies, introduced in the 0 high-speed integrated detection train Application. The results show that the complete set of wheel and rail interaction mechanics parameters including vertical force, lateral force, longitudinal force and wheel / rail contact position can be obtained continuously under complex operation conditions by using this technology. Dynamic research to create conditions for further research. This paper also discusses how to use the wheel to improve the dynamic simulation technology of the wheel-rail system of high-speed railway.
