비전머신 방법을 이용한 너트의 풀림 감지 시스템 연구

Nuts and bolts are the most commonly used fasteners for parts. However, the combined nut is loosened by wear and tear over time, harsh vibrations, or impact. Loosening of the nut inevitably leads to shorter machine life. This study uses a stroboscope which synchronizes with the machine rotating rpm to obtain a clear machine vision image of the nut loosening process, thereby it's facilitating the measurement of the loosening angle of the nut. The loosening process is tested using NAS3350 vibration test equipment. This results will be useful to analyze the nut loosening process. Ultimately, this study is aimed toward the development of a more resilient nut that is resistant to vibration and torque.
