Abstract

Hydraulic excavator is important mechanical equipment in engineering construction, which is widely used in mining enterprises, construction industry, etc. Variable axial piston pump is the main power component of hydraulic excavator. The negative flow control variable axial piston pump is deduced and the mathematical model is established. The dynamic simulation model of negative flow control variable axial piston pump is built by using SIMULINK in MATLAB software, and the simulation analysis is carried out. The influence of the main parameters of negative flow control mechanism on the dynamic characteristics of negative flow control variable axial piston pump is obtained, which provides a reference for the parameter design of negative flow control mechanism.
