Abstract

Abstract: Due to valve port commutation of traditional hydraulic impact system caused valve leakage. For the above shortcomings, an improved structure principle of the new type of non-valve controlled hydraulic impact system was proposed establishing dynamic equations of impact system andconducting simulation analysis based on AMESim. Due to the simulation results which was inconsistent with design goal, two improvement schemes were proposed adding throttle device and controlling inlet and outlet circuit. The simulation results suggest that the working performance of impact system has been improved by adding throttle device, and its efficiency has been increased from 11.8% to 18.3% when the diameter of orifice is 6.5mm; its efficiency has been increased from 11.8% to 26.4% by controlling inlet and outlet circuit, the improving effect is very significant, and it achieves the expected design goals. The study of the improved design scheme of non-valve controlled hydraulic impact system provides technical reference for the design and theoretical research of hydraulic impact system.
