Design and Analysis of Paver Walking Hydraulic System Based on AMESim

According to the technical characteristics of the structure of road paving and crawler paver in China, the working principle of crawler paver hydraulic walking system is analyzed, and the walking hydraulic system of paver is designed and studied according to foreign design scheme. On the basis of establishing the actual working conditions of the paver, the hydraulic system components are selected, and the AMESim platform is used for the modeling and simulation of the two schemes. The simulation results show that the flow rate and the speed of the actuator are proportional to the valve port opening size. The required flow of the working loop does not have to do with the external load, but only with the area size of the multiplex valve opening. The motor port pressure and the motor flow is stable at 7.5 L/min under different slope conditions, indicating that this system is reliable and can provide reference for the innovative design of the hydraulic system of the paver walking mechanism.
