MOTION ANALYSIS AND DESIGN OF ACCUMULATOR FOR HYDRAULIC ROCK DRILL
（College of Mechanical and Electrical Engineering,Central South University of Technology, Changsha 410083）
Abstract:A concept about the stretching ratio(β) of the hydraulic accumclator diaphragm has been put forward, and it was pointed out that in case of the stretching ratio(β) be equal to 0.5 the corresponding gas volume and initial pressure are beneficial to the improvement of the diaphragm s service life.
Key words: hydraulic accumulator diaphragm service life stretching ratio parameter design motion analysis
