Dynamic Characteristic Analysis and Simulation of Hydraulic System for Leveling Drilling Rig Outriggers

The leveling procedure of drilling rig outriggers based on electro-feedback of angle sensor is introduced, proportional directional valve model is built, and dynamic characteristic analysis for a quarter of system is done in this paper. Piston＇s response characteristic in terms of the input displacement of proportional valve and load distur-bance is deduced, HCD library for the proportional valve of drilling rig is simulated, at the same time, AMESim model building for the hydraulic system of drilling rig and system optimization are performed, which may supply reference for leveling construction machinery and other supports.
