摘要
扼要叙述和分析液压摆锤式试验机因测力机构参数改变，试验机安装不正确，摩擦阻力产生误差的原因，提出对产生的误差因素进行综合分析，不能用简单方法消除即可的观点。
It was analyzed that reasons for the error caused by some cases such as hydraulic Charpy machine tester parameters changing, incorrect installation of machine tester, error caused by frictional resistance. The point of comprehensive analysis methods in errors analyzing were raised.
