Research on Positive Control System with Synthetic Pilot Pressure of Excavator
摘要
Abstract
Based on the analyses of the working mechanism of a positive control system of excava- tor,a new type of positive control system with synthetic pilot pressure was designed. The hydraulic model was established. The transfer function of the spring deformation to the flow of the variable de- livery hydraulic pump was obtained. The system was simulated compared with conventional positive control system. The simulation results show that the responsing time is fast, the max overshoot of the positive control system with synthetic pilot pressure is less and the system is stable. The precision of the matched flow and the power efficiency are higher with less energy loss in the positive control sys- tem with synthetic pilot pressure than in the conventional positive control system.关键词
