摘要:
为了提高光纤光栅的测试水平,研究了相似模拟实验中光纤光栅传感测试的温度补偿方法。采用了不受力温度补偿法。将温度补偿光栅埋设于模型外的相似材料模块中。模型开采过程中模块仅感受温度的变化,不受任何外力; 模型内的测试光栅同时感受温度和应变的变化。实验表明,在外界温度变化的情况下,温度的影响作用明显,因此,剔除温度的影响很有必要。使用不受力法可以消除温度的影响,解决了相似模拟实验中光栅测试的交叉敏感问题,提高了测试的精度。
Abstract:
To improve the testing level of FBGs, the temperature compensation method of the FBG sensing in simulation experiments was studied. The compensation method without strain was applied. The compensation grating was embedded in a simulation lump outside the model. During mining, the grating in the lump experienced temperature only, and the testing gratings in the model were affected by temperature and strain simultaneously. The result indicates that the influence is obvious when the temperature changes. So, it is necessary to eliminate its influence. It can be achieved by the method without strain. The cross sensitivity problem is solved, and the precision is proved.
