超声导波技术越来越多地应用于石油和天然气工业中各类管道的无损检测.但管道中的超声导波会涉及复杂的传播与交互问题, 因此需要利用仿真手段指导实验设计及理论研究方向, 而如何保证有限元建模仿真的正确及高效是首要考虑的问题之一.针对管道点蚀型缺陷的导波检测仿真研究, 提出了基于多量化评估指标综合分析实现仿真系统参数设置的优化方案, 以保证超声导波建模仿真的准确和快速.进一步以网格划分和时间子步这两个仿真参数为例进行分析讨论, 并将仿真优化所得结果和实验研究结果进行了对比.此工作可为通过仿真手段进一步研究及应用超声导波技术提供理论支持.“,”Ultrasonic guided wave (UGW) technique is used increasingly for the nondestructive testing of different types of pipelines in oil and natural gas industries. However, the ultrasonic guided wave in pipeline usually involves complicated problems of propagation and interaction, therefore, it is necessary to make use of simulation analysis to guide the direction of theoretical research and experiment design. How to ensure the accuracy and efficiency of finite element modelling simulation in the practice of guided waves is one of the problems to be concerned firstly. Aiming at the guided wave test simulation study of the pitting defect in pipeline, in this paper, an optimization scheme is proposed for achieving the parameter setting of simulation system based on the comprehensive analysis of multiple quantitative evaluation criteria so as to ensure the accuracy and efficiency of the modelling simulation of ultrasonic guided waves. Furthermore, taking the simulation parameters of grid division and time sub-step as examples, analysis and discussion were conducted, the simulation optimization results and experiment results were compared to verify the effectiveness of the optimization scheme proposed in this paper. The work in this paper provides a theoretical support for the further study and application of ultrasonic guided wave technique through simulation means.
