薄板水浸超声穿透法自动检测系统设计

北京理工大学珠海学院2020届本科生毕业设计Design of automatic detection system of ultrasonic penetrationmethod for water immersion of thin plateAbstractWith social development,there's no subst itute for Nondestructive testing when itcomes to improve the comprehensive national power.Ultrasonic testing accounts for45%in researches of Nondestructive testing.And water immersion ultrasonic testingis a more prominent part of ultrasonic testing.For its strengthes in non-polution andautomatic operation,it is widely applicable.In this paper,a high-precision,high-speed,durable and beautiful scanning device for steel sheet has been made after a deepunderstanding of the principle of water immersion ultrasonic testing.I endeavor towrite relevant programs to control the movement of scanning platform,as well as tolocate and quantify defects and present them through intensity map through the imageprogramming language LabVIE W.This kind of automatic detection can greatlyreduce people's workload and the probability of error,and can be used in the pipelineto obtain higher economic benefits and work efficiency.Keywords:water immersion ultrasonic testing;Labview;automatic detection;steelsheet;penetrating method
