Research on Characteristics and Key Design Parameters of a Pilot-Assisted Load Control Valve
Abstract:
This paper reports the simulation and experimental results of a type of widely used load control valve. The investigated load control valve is usually applied to the mobile crane booming hydraulic circuit. It is used to balance the overrunning load due to gravity and to modulate the flow of oil when lowering the load. The load control valve has a significant influence on the performance of mobile crane booming system. A simulation model of the load control valve is established based on AMESim, moreover, a bench-test is conducted to evaluate the performance of the load control valve. The simulation results and the experiment data agree well and both results show a good performance of the valve. Further study of the effect and the inner principle of the key design parameters of the load control valve are also presented.
