一、前言冲击能量是凿岩机最重要的性能指标。我国目前在生产检测中广泛采用的机械试验台是五十年代由苏联引进的,这种方法已十分陈旧,其原理、精度和测试范围均存在较大问题,远远不能满足凿岩机生产和发展的需要,近年来在国际上已广泛采用应力波法测定凿岩机的冲击能,并于1981年纳入冲击式气动工具性能试验的国际标准(ISO2787)。为了使我国此项检测技术达到国际先进水平,根据机械工业部下达的科研任务,天水风动工具研究所和长沙矿冶研究院自1982年合作进行了此项研究工作,经过近两年的工作,目前主要技术关键已经突破,达到了预期要 First, the preface Impact energy is the most important performance indicator rock drill. At present, the mechanical test bed which is widely used in the production testing in our country was imported from the Soviet Union in the 1950s. This method has been very old, and its principle, precision and test range all have big problems, far from meeting the requirements of the production and development of rock drills In recent years, the impact energy of rock drill has been widely used in the world by the stress wave method. In 1981, it was incorporated into the international standard for the performance test of impact pneumatic tools (ISO2787). In order to make our detection technology reach the international advanced level, according to the scientific research mission issued by the Ministry of Machinery Industry, Tianshui Fengdonggongju Research Institute and Changsha Institute of Mining and Metallurgy conducted this research work since 1982, after nearly two years of work At present, the key technical breakthroughs have been achieved and the expectation has been reached
