基于LabVIEW的应变测量系统的设计与应用

Design and Application of Strain Measurement System Based on LabVIEW

结合虚拟仪器及其LabVIEW软件的优点,设计了一种基于虚拟仪器的应变测量系统。在应变测量原理的基础上,以经纱张力测试为例设计了应变测量系统的软硬件结构,验证了该测量系统较传统系统的优越性。结果表明,系统硬件结构简单,操作方便,同时能够充分发挥计算机在数据计算、传输、存储和显示等方面的巨大优势。

A system of strain measurement based on virtual instrument is designed, and it com- bines the advantages of virtual instrument and Lab VIEW software. Based on the principle of strain measurement, hardware and software framework of strain measurement system is designed case study in test of warp tension,and The advantages of this measuring system is verified over traditional systems. Results show that the system has advantages of simple structure, convenient operation, and which can give full play to the powerful advantage of computer in data calculation,transmission, storage and display.
