-
摘要: 提出了基于进化规划算法的加载流体管道中的导波频散方程求解方法，将进化规划算法引入到存在能量衰减的管道频散方程的求解中，进化规划仅采用突变控制进化过程，相比其他求解方法，该求解方法更便捷。利用磁致伸缩导波检测技术检测充水管道，试验所得的导波速度均落在通过该算法求得的导波频散曲线上。Abstract: A solution method of guided wave dispersion equation in the fluid-filled pipe is presented based on evolutional programming. The evolutional programming is introduced into the solution of pipe dispersion equation with energy attenuation, and it controls the evolutional process only with saltation. Compared to other solution methods, the solution method of dispersion equation based on evolutional programming is more convenient. The velocities measured during the NDT of fluid-filled pipes based on magnetostrictive guided wave were shown to be well matched with the velocity curve calculated by the presented method.
