摘要
基于等强度标准梁应变实验 ,对光纤光栅与电阻应变片两种应变测量方法进行了实验对比 .结果表明 ,光纤光栅方法应变测量数据的线性度、灵敏度与理论计算值符合得很好 .光纤光栅方法测量应变是可行的。
On the basis of the stress sensing experiments of equivalent strength standard beam, two strain measurement methods of fiber grating and resistance strain chip are experimentally contrasted. The studies indicate that the linearity and the sensitivity of fiber grating are well in agreement with those of theory. The measurement method of fiber grating is practical and effective.
