Abstract
Aimed at the problems in existing constant power variable pumps, such as complex structure, high cost and sensitiveness for oil pollution, a new variable displacement mechanism of constant power axial piston pump is proposed. The principle of the new variable displacement mechanism is introduced, and the static performance is analyzed. Simulation platform is built in ADAMS and AMESim, and the co-simulation is run on the platform to analyze the dynamic performance and its influencing factors. The results show that the new variable displacement mechanism has fast response and small overshoot. The pump power can be controlled exactly by the controlling pressure. The piston diameter, lever arm length and power control gain coefficient have obvious effects on the dynamic performance.
