Abstract

Hydraulic excavators have been one of the most popular devices in the various industries for construction, forestry and agriculture etc. Because the excavators generally work in poor environment, the various organizations study to automate those. In this paper, a hydraulic simulation for evaluation of automatical excavation system is presented. It is using the AMESim based on the 1.5 ton excavator with fixed displacement pumps, and operated by signals those control pilot pressure to spools of the main control valve. The main control valve is regarded that only consists of boom, arm and bucket. This simulation program is expected to apply to evaluation of the controller for automatic excavation system and to estimate of effect in accordance with change of some components or parameter.
