Abstract

In this study, we analyzed the stick slip characteristics through friction experiments on materials used in mechanical and electronic products, and propose improvements to reduce abnormal noise generated inside refrigerators. To analyze the stick slip phenomenon of the materials, we fabricated a friction testing device and conducted friction experiments. Additionally, we measured the vibration and noise levels of internal components to analyze the occurrence and location of abnormal noise inside the refrigerator. By comparing the results of the refrigerator’s phenomenon analysis and friction experiment, we confirm that the abnormal noise occurring inside the refrigerator is caused by the stick slip phenomenon of internal components. Finally, to propose improvements for abnormal noise reduction, we performed friction experiments using the Taguchi method and validated the performance of the proposed improvements by applying them to refrigerators.

본 연구에서는 기계전자 제품에 사용되는 소재의 마찰실험을 통해 스틱슬립 특성을 분석하고 냉장고 내부에서 발생하는 이상소음을 저감하는 개선안을 제안하였다. 소재의 스틱슬립 현상을 분석하기 위해 마찰실험장치를 제작하고 마찰실험을 수행하였다. 또한 냉장고 내부에서 발생하는 이상소음의 현상과 위치를 분석하기 위해 내부부품의 진동과 소음 레벨을 측정하였다. 그리고 냉장고 현상분석 결과와 마찰실험 결과를 비교하여 냉장고 내부에서 발생하는 이상소음은 내부부품의 스틱슬립 현상에 의한 것임을 확인하였다. 마지막으로 이상소음을 저감하는 개선안을 제안하기 위해 다구찌 기법을 이용한 마찰실험을 수행하였다. 그리고 개선안을 냉장고에 적용하여 성능을 검증하였다.
