Abstract
An excavator consists of several hydraulic components which include pumps, a main control valve and cylinders etc. It operates by the linkage of the components. This paper is concerned with development of a hydraulic simulator for an excavator. The simulator has been developed using AMESim based on specifications of a 1.5 ton excavator. The excavator has been installed additional components to investigate an automated field robot; Electro proportional pressure reducing valve, electronic joysticks, angle sensors and a controller was installed at the excavator. The developed hydraulic simulator has the ability to represent with animation. The modeled MCV has been applied non-linear open area of spools.
