摘    要:针对固体火箭发动机纤维缠绕壳体状态监测中局部可能出现大应变情况,采用聚合物光纤布拉格光栅(polymer op-tical fiber Bragg grating,POFt3G)传感器对大应变进行检测;分析了湿度和温度对光纤光栅反射波长漂移量的影响,建立了湿度传感模型、温度传感模型和温度湿度混合模型.并通过MATLAB进行数值仿真,结果表明,反射波长随温度的升高而减小,随湿度的增加而增大,并受到温度和湿度的交叉影响,这与文献报道的实验结果比较吻合.

关 键 词:聚合物光纤光栅  固体火箭发动机  大应变  数值仿真  温度  湿度

Abstract:Polymer optical fiber Bragg grating(POFBG) sensors are adopted for large-strain detection in local parts during the monitoring of filament-wound case of solid rocket motor.The influences of temperature and humidity on reflected wavelength shift of POFBG were analyzed.The model was established dependence on the temperature change,humidity change and dual-parameter cross-change.The changes of temperature and humidity of POFBG were simulated by MATLAB.The results show that the Bragg wavelengths decrease with t...
Keywords:polymer optical fiber Bragg grating(POFBG)  solid rocket motor  large-strain  numerical simulation  temperature  humidity
