摘要
基于弹性波的波动方程反演提出压力管道的损伤检测方法,根据直杆的波动方程,用直杆的横截面积作为反演参数模拟管道损伤,在优化思想下利用序列二次规划对其进行数值反演,达到损伤识别。
The detection of the pipe's damage is proposed in this paper. The area of the pipe is directly considered as the parameter of the undamaged detections to simulate damage in the pipe while corroding or others. The detection of the damage can be received by the numerical inversion based on quadratic optimization algorithm.
