Abstract


In recent years, with the development of hydraulic technology, full hydraulic leveled machine is the trend of motor grader instead of mechanical, slowly become a ordinary machine field mainstream. The grader is a kind of typical traction type machinery, it’s load conditions is diversiform, requirements, speed and load between traction with adaptive ability. However, single pump hydraulic shunt pair of motor drive the full hydraulic of motor grader, because of it’s own characteristics, the full hydraulic of motor grader in solving driving and homework synchronization performance has a lot of problems, especially in the more serious when appear slip.This thesis to a particular of the full hydraulic of motor grader as the research object, From the most basic of motor grader’kinematics and dynamics of aspects begin, determine slip rate and the relationship between the external load. Use the knowledge of traction dynamics with the full hydraulic of motor grader system matching parameters, special according to requirements of the full hydraulic of motor grader synchronicities, this paper puts forward synchrony hydraulic driving system running of the full hydraulic of motor grader concrete parameters reasonable matching.The fuzzy incremental PID control of hydraulic motor, AMESim and MATLAB/Simulink through joint simulation software simulation, and the simulation results verify the dynamic matching parameters based on traction on the basis of full hydraulic leveled the feasibility of synchrony research machine; the fuzzy incremental PID control of hydraulic motor rationality and accuracy.
