Research on lifting cylinder's pressure stability control method of active scraper

Abstract

This paper comprehensively introduces a pressure buffering approach of Active Scraper's lifting cylinder, with special analysis on the shortcomings of Rexroth RSM2 Stability Module. This paper also puts forward a new type of Pressure Stablizing Control Method of Hydraulic Lifting Cylinder, accompanied by simulation analyses and experiment researches on working modes of this system. The result shows that the new Pressure Stablizing Control Method can effectively reduce the pressure of the hydraulic system when load mutation causes impact, thus it protects the hydraulic cylinder, so as to prolong the service life of hydraulic components.
