根据材料的机械或工艺性能实验,对这些材料进行研究是与发展适用的材料试验机紧密相联的。这些适用的材料试验机必须满足根据定义所规定的要求在材料上重新产生应变,尤其是要注重负荷的影响,负荷——时间曲线图以及在测量中指示与记录的误差要小。材料试验机结构的构思,最初是基于以机械测量方式的称量仪器演绎来的,也就是从用两个样品相称量的平衡结构发展起来的。现以几个例子为代表。这些例子对于了解和研究迄今为止的试验机的历史及其现状是很有意义的。 According to the mechanical or technological performance tests of materials, the study of these materials is closely related to the development of suitable material testing machines. These applicable material testing machines must meet the requirements of the definition to regenerate strain on the material, in particular to focus on the effects of the load, load-time diagrams, and errors in the indication and recording of the measurements. The concept of the structure of the material testing machine was originally based on a mechanical measuring method performed by a weighing apparatus, that is, developed from a balanced structure in which the two samples were weighed. Here are a few examples. These examples are very meaningful for understanding and studying the history of the testing machine so far and its current status.
