Simulation Study of Single Steel Wheel Vibratory Roller System Based on MATLAB
Based on MATLAB/Simulink software,an engine system and the moving and vibrating hydraulic system for a single steel wheel vibratory roller are completed.In addition,the corresponding dynamic model of the moving and vibrating wheel is analyzed and established.In order to facilitate test engineers to simulate the driving process,an interactive interface is built according to IO and CAN messages from the control strategy.At the same time,the roller's 3 D action demonstration is realized by MATLAB/Simscape.Model parameters are de-signed and matched according to the information of the real vehicle.So the basic functions such as hydraulic walking,engine speed setting and self-starting vibration are tested on this basis.The simulation results show that the MIL test environment established in this paper can simulate and verify the control strategy of single steel wheel vibratory roller.
