Study on Hydraulic Circuit Simulation Based on MSC·EASY5 for the Arm of Excavator

Abstract:

In this paper, a hydraulic excavator is used as an example, and a model of the hydraulic circuit of the excavator arm is established using the graphical modeling method of EASY5. Through the simulation and analysis of the results, it can be seen that the simulation results can accurately simulate the dynamic characteristics of actual hydraulic circuit, and show the variation of the pressure in the hydraulic cylinder chambers. It not only provides a basis for the system performance analysis and the further improvement, but also provides a new method for the optimization design and overall performance analysis of the engineering machinery hydraulic system. And it also provides a new idea of design for the development of new product.
