要分析WE系列万能材料试验机误差形成的原因要先从它们的工作原理入手,WE系列万能材料试验机属于液压摆锤式试验机,工作原理如下,由油泵进入工作油缸的油同时进入测力油缸,使测力活塞受力f,设S1和S2分别是工作活塞和测力活塞的有效面积,F是试件所受到的力,也就是工作活塞所受到 WE series of universal testing machine to analyze the reasons for the formation of error should start with their working principle, WE series of universal testing machine belongs to the hydraulic pendulum test machine, the working principle is as follows, into the working oil from the pump while the oil into the force Cylinder, the force measuring piston force f, set S1 and S2 are the working piston and the effective area of ​​the measuring piston, F is the force suffered by the specimen, which is the work of the piston received
