引伸计是测量构件及其他物体两点之间线变形的一种仪器,通常由传感器、放大器和记录器三部分组成.在使用中有很多人反应引伸计夹不紧,是不是质量有问题,其实不是引伸计的质量问题,而是使用方法的问题.

The extensometer is an instrument for measuring the linear deformation between two points of components and other objects. It is usually composed of sensors, amplifiers and recorders. Many people in use react that the extensometer is not clamped tightly, whether there is a quality problem, in fact, it is not the quality problem of the extensometer, but the problem of the method of use.

在装夹引伸计时,将引伸计轻轻拿起,把标距杆垫片卡在力臂与标杆之间,压紧两力臂,使两刀刃垂直接触试样,用弹簧或橡皮筋将引伸计绑在试样上,装好后取出标距杆垫片,使力臂与标距杆之间保持0.5mm的间隙.

When clamping and extending, the extensometer is gently picked up, the spacer of the benchmark bar is clamped between the force arm and the benchmark bar, and the two force arms are pressed so that the two blades contact the sample vertically. The extensometer is tied to the sample with a spring or rubber band, and the spacer of the benchmark bar is taken out after loading, so that the gap between the force arm and the benchmark bar is kept at 0.5mm.

注意事项:

Matters needing attention:

1. 电子澳门新浦京8455com在试验前必须检查,以免造成引伸计损坏.

1. The electronic universal testing machine must be checked before the test, so as not to cause damage to the extensometer.

2. 要保护好电子引伸计,不要摔碰,刀口保持锋利.

2. To protect the electronic extensometer, do not fall and keep the knife edge sharp.

3. 标距杆两端的螺丝钉不要取下,以防两臂开度无限制张开,造成应变片及弹簧片永久变形,使得引伸计损坏.

3. Do not remove the screw at both ends of the benchmark rod to prevent the opening of the arms from opening indefinitely, resulting in permanent deformation of strain gauges and spring sheets, which may damage the extensometer.

值得一提的是,有的电子澳门新浦京8455com夹具在夹紧试样的时分会发生一个初始力,所以记住必定要把初始力消除以后再夹持引伸计,这样引伸计夹持的标距才是试样在自在状态下的原始标距.

It is worth mentioning that some fixtures of electronic universal testing machine will produce an initial force when clamping the sample, so remember that the initial force must be eliminated before clamping the extensometer, so that the distance held by the extensometer is the original distance of the sample in its own state.
