摘要
讨论力学实验中CAT应用问题,建立了两套实验装置,并开发了相应的可用于现场实际测试的应用软件.一是基于微机和传感器技术的CAT系统,可用于工业生产实际中的压力、位移等物理量的测量.二是利用YJ—4501A静态数字电阻应变仪提供的串行通信接口,实现实验数据自动采集、分析处理,完成了应力应变测试的应用软件开发,该软件可用于材料力学的实验教学和大型构件应力应变的现场测试.
Several problems such as hardwares and software development about CAT are discussed in this paper. Two sets of testing equipment, applied for testing, are built. One is composed of a computer and several sensors. It can be applied in the test of physical measures such as pressure, displacement, distortion etc, and its application software is developed. The other is made up of a computer and a strainmeter YJ-4501A .The testing data acquired by the strainmeter YJ-4501A can be transmitted to the computer through a serial communication port RS-232 and can be analyzed and displayed by the computer simultaneously. The softwares are also developed for tests in industrial production and in teaching material mechanics.
