Transmission System And Slip Performance Analysis Of Multi-function Paver With Large Width And Thickness

Paver is mainly used for paving various materials as road base and pavement surface,which plays an important role in the construction of highways. However, the conventional paver also has its drawbacks: small paving width, not enough paving thickness, single working device and high cost. In order to overcome these drawbacks, a company has produced a truss multi-function paver with large width and thickness. This paper takes the paver as the research object, and analyzed its’ the transmission system and slip performance.This paper analyzed the kinematics and dynamics of the crawler walking system, and analyzed the relationship between traction force and slip rate. Also, it studied the adhesion performance of tracked vehicles and the paving resistance of the paver deck. The paper determined the electric drive scheme of the paver, matched the parameters of the main components according to the matching principle of the electric drive system parameters, and the basic parameters of the driving motor and generator are calculated. In this paper, the model of the equivalent paver and pavement are established by using multi-body dynamics software RecurDyn. Then, the multi-function paver with large width and thickness is simulated. The slip of the paver and the drive torque of drive sprocket among the four-crawler travel unit is researched in the following condition: no load running on the flat road; full load running on the flat road; offset load running on the flat road; full load running on the 9%longitudinal slope road. The relationship between traction force and slip rate of the paver is also analyzed. From the simulation results, it is found out that the slip performance and the working performance of the paver and the torque of the driving sprocket under several conditions. The model of the constant speed control system of the driving motor is also established by the SIMULINK. The simulation analysis of the constant speed control system of the paver is carried out based on the co-simulation of Recur Dyn and SIMULINK, and the result of simulation achieves the prospective effect. In this paper, some meaningful conclusions are drawn, which will provide theoretical basis for the development and research of the multi-function paver with large width and thickness.
