应用通用微机改造万能材料试验机的测试系统

利用通用微机对WE-300型万能材料试验机的进行技术改造，建立一套基于微机和传感器技术的测试系统。实现了试验过程的自动化。讨论其技改方案的确定、传感器的安装与标定以及所开发的应用软件特点等几个技术问题。试验结果表明：所建立的测试系统可实现实验数据的自动采集、分析和处理，绘制出整个试验过程的试验曲线，同时还可以提高万能材料试验机的试验精度和试验效率。

The application of computer to the technological reform of the test system in a universal testing machine

Computer and sensor technology are applied in the technological m od ification of a universal testing machine WE-300. A new testing system is built up. It can acquire, analyze and process the testing data automatically. The for ce-deformation curve of a testing rod in tension can be acquired entirely. The testing accuracy and efficiency can also be improved simultaneously. Several t echnical problems are discussed, such as the choice of the project for the techn ical reform, the assembly and demarcation of the tensors and the feature of the software for the tests in material mechanics etc.
