摘要
研制了农业物料力学试验装置及其测控系统 .该系统可用于农业物料力 -变形、蠕变及松弛试验 .由位移、力等传感器、数据采集卡、开关量输入输出卡和计算机组成试验过程控制及数据采集系统 .应用结果表明该系统工作可靠 ,操作简便 。
A test device for strength and rheological properties of agricultural materials was described.It could be used for testing of stress strain, creep and stress relaxation of agricultural materials. An automatic data acquisition and control system for the test device was developed. A displacement sensor, a load sensor, a high performance DAS card and a digital I/O card were interfaced with a microcomputer for this purpose. Performance of the test device was demonstrated by using it in testing for firmness of peach and pear.
