Simulation of Ultrasonic Testing of 3D Sound Field of Cylinder Based on Multi-gaussian Beam Model
摘要
Abstract
In combination with the cylinder actual Defect detection requirements,this paper adopts the multi-Gaussian beam model to simulate 3D sound filed distribution of ultrasonic testing. According to theory of water immersion ultrasonic detection,the peocess have four phases what are ultrasonic probe emission ,fluid coupling medium transmission,the spread of solid-liquid interface and solid workpiece ,the model is established and the simulation results are obtained. The different directions of sound field changes in 3D coordinate is analyzed. The results show that multi-gaussian beam model is effective and accurate in simulating the 3D sound field .The result provides a theoretical basis for the defect detection of cylinder workpiece.关键词
