本文为了使广大读者对电子万能试验机有个全面了解,从其发展入手,根据主要技术演变过程划分成三个“时代”。并简要讨论了不同“时代”的结构原理,性能指标以及由于采用组合设计思想使试验功能进一步扩大,从而希望能为研制、生产,选用该种试验机有所帮助。文中图5幅,表6个。 In order to make readers have a comprehensive understanding of electronic universal testing machine, starting from its development, this article is divided into three “times” according to the main technological evolution. And briefly discussed the structure principle and performance index of different “times”, and further expanded the test function by adopting the combined design idea, hoping to be helpful for the development, production and selection of the testing machine. The picture in Figure 5, Table 6.
