<正>The working principle of a new hydraulic breaker operated jointly by gas and hydraulic flow which has a reasonable structure,high efficiency and long piston life-span,is analyzed,and the optimal power distribution ratio of the sealed nitrogen gas to the high-pressure oil in the process of piston impacting is studied.Through theoretical analysis,optimization simulation and detailed calcu- lation,it is determined that the impact system has optimal mechanical performance and highest effi- ciency when the distribution ratioΦis between 0.3 and 0.5.The theoretical result is also verified by reneated tests.
