| 拉伸试验一般是将材料试样两端分别夹在两个间隔一定距离的夹具上，两夹具以一定的速度分离并拉伸试样，测定试样上的应力变化，直到试样破坏为止。 In tension test, the two ends of the material sample are clamped on two fixtures with a certain distance, www.lvhejizhujian.cnwww.yanglaoyuanq.com.cnwww.diandongmenq.com.cnwww.zhonglizhuzao.com.cn www.yanglaoyuanc.cnwww.yazhujian.net.cnand the two fixtures are separated and stretched at a certain speed. The stress changes on the specimen are measured until the specimen is destroyed. 拉力机拉伸试验是研究材料力学强度最广泛使用的方法之一，需要使用恒速运动的。按载荷测定方式的不同，早期大体可以分为摆锤式拉力试验机和电子拉力试验机两类。 Tensile test of tension machine is one of the most widely used methods to study the mechanical strength of materials, which requires constant speed movement. According to the different ways of load measurement, the early stage can be roughly divided into pendulum tension tester and electronic tension tester. |
