Research of Test Method for the Bogie Rotary Torque

摘要

Rotary torque is one of the important parameters of the bogie.A scheme of the rotary torque test for the bogie was put forward,and the homogeneous matrix based on the Euler angle was introduced,the model of inverse pose of the slewing platform was built.Also,it implemented the real-time solution by means of simulink,and fitted the curve of hydraulic cylinder expansion amount and time by use of the MATLAB curve fitting toolbox.The method that took the motion curves of the actuators as the control input is put forward,which was of great value and laid the foundation for the test of rotary torque.
