基于导波阵列的挡潮闸门板件损伤整体成像方法研究
Research on the overall imaging method for damage of tidal gate plate components panels based on guided wave array
摘要
Abstract
Tidal barrier gates are subject to corrosion fatigue degradation,posing a risk of failure.Regular inspections are necessary to ensure their safety.However,the existing nondestructive testing technology is mostly point-by-point testing and speculating surfaces with points,which carries a risk of missed detection.Therefore,a method for overall inspection of plate components based on guided waves is proposed.A damage index based on the amplitude of the damage reflected wave is proposed to achieve damage visualization based on guided wave reflection and sensor arrays,accurately locating and imaging single and multiple damages.On this basis,a prototype of the guided wave detection device is developed,and verification field tests are carried out relying on actual projects.The research shows that this method improves the coverage rate and accuracy of tidal gate inspections,providing convenience for the inspection of high zone gates.关键词
