摘要:
为研究压力管道裂纹缺陷的锁相红外热成像检测技术，提升压力管道运行的安全性。针对具有大曲面结构的压力管道内部缺陷锁相红外热成像检测的难点问题，采用数值模拟方法研究分析加载热源频率对管道内部轴向裂纹、环形裂纹缺陷辨识的影响规律，提出以表面温度相位差峰值以及展宽为依据的裂纹缺陷检测最优频率的确定方法，讨论不同深度裂纹缺陷检测的温度相位差与热源频率的关联规律。研究结果表明：锁相红外热成像方法能够应用于大曲面结构压力管道内部裂纹缺陷检测，对于压力管道内特定深度的缺陷辨识存在最优的热源频率范围。研究成果可为锁相红外热成像技术在压力管道安全检测领域的应用提供参考。
Abstract:
In order to study the lock-in infrared thermography detection technology of crack defects in pressure pipeline and improve the safety of pressure pipeline operation,aiming at the difficulty of lock-in thermography detection of internal defects in pressure pipelines with large curved surfacestructure,the numerical simulation methods was used to study and analyze the influence of the frequency of loading heat source on the identification of axial and circumferential crack defects in pipeline.A method for determining the optimal frequency of crack defect detection based on the peak and broadening of surface temperature phase difference was proposed,and the correlation between the temperature phase difference and the frequency of heat source for crack defect detection at different depths was discussed.The results show that the lock-in thermography method can be applied to the detection of internal crack defects in pressure pipelines with large curved surface structure,and there is an optimal frequency range of heat source for identifying defects at specific depths in pressure pipeline.The research results can provide a reference for the application of lock-in infrared thermography technology in the field of safety detection of pressure pipelines.
