Abstract

Since real-time monitoring system like a fault early detection has been very important, infrared thermography technique as a new diagnosis method was proposed. This study is focused on the damage detection and temperature characteristic analysis of ball bearing using the non-destructive infrared thermography method. In this paper, for the reliability assessment, infrared experimental data were compared with the frequency data of the existing. As results, the temperature characteristics of ball bearing were analyzed under various loading conditions. Finally it was confirmed that the infrared technique was useful for real-time detection of the bearing damages.

결함을 조기에 발견하기 위한 실시간 모니터링 시스템은 적외선 열화상 기술을 중점으로 구성된다. 본 연구의 중점은 비파괴 적외선 열화상 기법을 사용하여 볼베어링의 손상 검출 및 온도 특성 분석이다. 본 논문에서는 신뢰성 평가를 위한 적외선 실험 데이터와 기존의 주파수 데이터를 비교했다. 실험을 통해 베어링의 온도 특성에 따라 다양한 손상 상황을 분석했다. 본 논문의 실험의 결과로부터 적외선 열화상 기법은 실시간으로 동작 상태에 하중을 받는 볼베어링의 손상 탐지를 위한 매우 유용한 기법임이 확인되었다.
