NDS-1型扭转试验机由于购置时间较早,其测试系统已不能满足试验工作的需要,必须进行改造。介绍了 NDS-1型扭转试验机测试系统技术改造工作的过程,改造后的测 试 系 统 除 具 有原系统的全部功能外,还可以实时保存试验数据、绘制试验曲线以及计算试验结果,并可随时查看已完成试验的数据及分析结果,整个系统界面友好,操作直观方便,而且整个改造花费成本不多,对在实验室中完成其他老旧设备的技术改造积累了一定的经验。

NDS-1torsion tester is the main test equipment on torsion experiment in author laboratory,but itwas purchased early,it was not able to satisfy the need today,the test system needs development.It was introducedin detail how to improve the test system,after improvement,the system not only had the complete functionoriginal,but also can work on preserving data momentarily,drawing curve,calculating test result,and showingdata analysis result of complete experiment which already finished.Frame of interface simple and harmoniously,easy to operate,moreover,it was no costs much,good for accumulating experience of other system improvement inthe laboratory.
