Research Based on the Simulink excavator hydraulic system dynamic simulation

摘要

This article first to the excavator bucket rod of hydraulic circuit based on the establishment of basic hydraulic components of the mathematical model, using the Simulink simulation software to build the overall hydraulic circuit simulation model;;according to the actual situation of module parameters to the appropriate value, the complex and changeable load is simplified into four different operating conditions, by inputting different signals to simulate different operating condition simulation, finally through the study of the parameters on the dynamic characteristics of hydraulic system of excavator working device effects, the results of the simulation analysis, put forward the corresponding improvement measure.
