A Simulation on the Hydraulic Control Characteristics of Excavator Using Load Sensing System

부하감지시스템을 사용한 굴삭기의 유압제어특성 시뮬레이션

The purpose of this paper is to construct a computer simulation system which can analyze and design the hydraulic excavator Theoretical analyses are performed on the hydraulic circuit and attachment of excavator with load sensing system. Databases are constructed for control valve opening areas, horsepower control and for load sensing regulator. For hydraulic components modularized programming techniques are applied which is expected to be utilized for software development of fluid power system. Through simulation an information of any point in hydraulic circuit can be obtained.
