A Study on the Characteristic Analysis of the Load-sensitive Hydraulic Pump Control System
부하 감응형 유압 펌프 제어 시스템의 특성 해석에 관한 연구
Abstract
In this study, the static and the dynamic characteristics of the load-sensitive hydraulic pump control systems of a hydraulic excavator were analyzed using the developed analysis tool. The results were compared with the experimental ones. To improve the static performance of the system, the system parameter effects on the controllable region and the pump pressure variation were studied. The parameters enhancing dynamic characteristics were also considered.
