랩뷰를 이용한 데이터 분석 프로그램 제작과 적용

Abstract

LabVIEW was a programming language that processes data using a graphical function. It has the advantage connection between measuring equipment and system. In addition it is easy making functions for users and then saved functions can be used other programming. In this paper programs developed to data acquisition and analysis. The program can working on a personal computer. This program was used to data acquisition and analyze elastic waves (acoustical emission (AE)) that generate as accumulated energy release inside when a material is deformed. Elastic wave generation was performed by Pencil Lead Breakage(PLB), Tensile test, Hydrogen Assisted Cracking (HAC). The developed program was able to acquire and analyze AE signals, and the results were similar to other studies using expensive equipment. Development of a LabVIEW program can save the cost of purchasing new expensive equipment. By modifying the developed functions, it is possible to shorten the new signal acquisition and analysis program development period.
