超特高压环氧绝缘件超声检测技术及典型缺陷声学回波特征分析

Dianci bileiqi
超特高压环氧绝缘件内部缺陷的可靠检测对于保障电力设备安全可靠运行具有重要意义。文中提出基于超声脉冲反射法实现超高压环氧绝缘件内部气孔、气隙、密度不均等缺陷的有效检出。论文基于声场仿真技术分析多时空尺度下超声波在环氧复合材料内的传播规律，探寻影响环氧复合材料内部缺陷检测灵敏度的关键因素，掌握不同缺陷直径、尺寸、深度下超声回波信号的特征。为验证理论分析有效性，搭建了超声检测试验平台并对特高压盆式绝缘子典型缺陷试样进行了相关的检测试验 ...

基于超声CT成像的钢-混凝土组合结构界面损伤识别研究

Jianzhu Gangjiegou Jinzhan
针对传统超声检测方法难以准确识别钢-混凝土组合结构内部缺陷的难题，提出了基于超声Computed Tomography （CT） 成像的钢-混凝土组合结构界面剥离损伤量化方法。研发了具有电磁屏蔽功能的磁吸式新型超声换能器，利用Akaike Information Criterion （AIC） 算法提取透射波初至的方法。基于所建立的正演数值模型和反演分析，系统性研究了Back Projection Technique （BPT），Algebra Reconstruction Technique （ART）
