As most of today’s a continuously variable transmission (CVT) adopt an electro-hydraulic control system, the role of electronically controlled solenoid valves play an important stature. This paper presents a dynamic modeling and simulation of CVT hydraulic system using Matlab-simulink package and analyzes the dynamic characteristics of the CVT hydraulic system in frequency domain.

Hydraulic Control System

Pump-control-motor hydraulic drive system is a common used volume speed-modulating loop in hydraulic control system. Aiming at the working conditions of the cutter head of the tunnel excavator used in the large underground excavation, a pump-control-motor hydraulic drive system was applied that composed of three variable displacement hydraulic pumps and eight hydraulic motors, which can control the rotate speed of the cutter head in real time. The simulation model of the pump-control-motor was established using the AMESim software. The relationships among the rotate speed, torque of the cutter head and the system pressure, system flow were investigated in detail under several typical working conditions in tunneling. The relevant results can provide theory references for design of pump-control-motor hydraulic control system in other occasions.
