光纤光栅应用于石蜡内部结构的特性监测
|
摘要
石蜡材料在造型及涂敷过程中,长时间处于熔融状态,与空气接触易氧化变质。为了准确研究石蜡内部结构,利用光纤光栅传感器体积小、外形可变且易于埋入结构内部等特点,设计了基于光纤光栅的石蜡熔-固态温度/应变无损监测系统。实验结果表明,石蜡内部温度从90℃下降至40℃左右时,应变仅改变170με;从40℃下降至25℃时,100min内应变改变750με,并且温度和应变呈线性关系。
Paraffin wax materials are in melting state for a long time in the process of molding and coating. It is easy to oxidize and deteriorate in contact with air. In order to study the internal structure of paraffin wax accurately, a non-destructive temperature/strain monitoring system for melting-solid state of paraffin wax based on fiber bragg grating(FBG) is designed by using the characteristics of small volume, changeable shape and easy embedding in the structure. The experimental results show that the strain changes only 170με when the internal temperature of paraffin wax decreases from 90℃ to 40℃; The strain changes by 750με in 100 minutes when the temperature decreases from 40℃ to 25℃, and the temperature and strain show a linear relationship.
