The Application of UT Simulation Technique in the Ultrasonic Testing of Reactor Pressure Vessel
-
摘要: 与实验研究相比, 超声仿真研究可提高对最基本的超声波回波产生机理以及超声波成像的理解且更为经济。建立数学模型后, 可以方便地改变各种参数进行研究, 以设计或优化超声检查工艺。以反应堆压力容器法兰-筒体焊缝为例, 利用超声仿真技术对其进行超声检查仿真研究, 系统介绍了超声检查的仿真过程和仿真结果。Abstract: Compared with experiment investigation, UT simulation technique can improve the comprehension of basic principle of the ultrasonic wave generation and imaging. It is more economy. When the mathematic module established, it is convenience to do the investigation by change the different parameters used to design or optimize ultrasonic inspection technique. This paper describe the application of UT simulation technique in the ultrasonic testing of reactor pressure vessel (as an example, flange to shell weld), in order to illustrate the process of simulation on ultrasonic inspection and the results of simulation.
