Research on Control System of Calibration Test Bench for Instrumented Wheelset Based on ARM
This article designs an ARM-based control system for instrumented wheelset calibration test bench to address the current development status of the control system for instrumented wheelset calibration test benches,hardware circuit design and software function development of the control system are completed,functions such as hydraulic loading control and servo motor control are implemented,and the relevant functions are tested.The results show that the control system of the ARM based instrumented wheelset calibration test bench has complete functions,rich resources,high integration and automation degree.The indexing control accuracy of the wheel set forward and reverse rotation is 0.42‰ and 0.46‰,respectively.The loading control accuracy of the left wheel vertical force,right wheel vertical force,left wheel lateral force,and right wheel lateral force under a load of 2 tons is 0.45‰,0.25‰,0.105％,and 0.160％,respectively,meeting the functional requirements of the calibration test bench.
