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要进行综合分析 ,不能用简单方法消除即可的观点
The article mainly narrates and analyzes the reason of hydraulic pendulum type testing machine due to the change of the parameters of the measuring mechanism, the incorrect installation of the testing machine and the error of the frictional resistance. It puts forward that the error factors should be comprehensively analyzed and can not be eliminated by simple method
