基于涡旋超声的钛合金孔洞缺陷检测方法
Defect detection method of titanium alloy holes based on vortex acoustic beam
摘要
Abstract
A novel vortex ultrasonic hole-detection methodology is proposed to address the pressing need for rapid and cost-effective internal defect detection within materials,leveraging the unique properties of vortex ultrasound.A systematic analysis was conducted on the propagation characteristics of vortex ultrasound within titanium alloy materials.The research findings reveal that the second harmonic signal detected at the center of the vortex ultrasound field can effectively ascertain the presence of internal pores in the material.Furthermore,the signal amplitude diminishes as the radial distance and depth between the pore and the center position increase,thereby defining the effective radial and depth detection ranges of vortex ultrasonic inspection and enabling qualitative localization of the pore's position.Concurrently,the amplitude at the vortex ultrasound center position escalates with the enlargement of the pore size,indicating its potential for quantitative assessment of pore dimensions.Numerical simulation results further corroborate that variations in the presence,position,and size of pores induce alterations in the amplitude at the vortex ultrasound center,thereby validating the efficacy and feasibility of vortex ultrasound for detecting pore defects in titanium alloys.This study is anticipated to furnish novel theoretical insights and methodologies for the swift detection of internal pores in materials.关键词
