Kuvaus

A Matlab/Simulation model is utilized to study the total energy consumption and power distribution of the micro excavator. The model consists of the hydraulic and mechanical systems related to actuation of front hoe, i.e. boom, arm, and bucket. The excavator is equipped with pressure and position sensors, from which the measurement data is collected for parameterization and verification of the simulation model. Two different duty cycles, named digging and loading cycle and leveling cycle, based on the JCMAS standard, are utilized in this study. The results indicate a formidable room for improvement, concerning the hydraulic system, since a power loss of as much as 60% is localized in the directional valve group.
