The modeling analysis of roadheader hydraulic walking system

If the control of the motor action is grasped correctly based on the hydraulic power control,the reliability of roadheader walking system could insure to protect the accuracy of the roadheader routes.In this paper,the basic structure of the hydraulic walking system of the roadheader is introduced firstly,the basic principle of the hydrostatic walking system of the roadheader is discussed,the key point of the hydrostatic walking system is analyzed and the model is built and the machine hydraulic walking system is simulated finally.The facts have proved that the construction of the system model has a good dynamic adaptability and stability.The hydraulic walking system is the key to the roadheader,which affects the effectiveness of the application of industrial boring machine directly.
