Abstract

This study provides the finite-element (FE) squeal-model predicting friction-induced noise with respect to several friction materials that have different friction characteristics. The friction curve and the corresponding friction noise were measured for four friction materials (Cu, Ni, Al, Mg) using the pin-on-disk and reciprocating friction system. The slope of the friction curve linearized at the sliding velocity was applied to the FE model. The unstable modes in the complex eigenvalue analysis were shown to correspond to the squeal frequencies that existed in the experiment.

본 연구는 마찰 특성이 다른 재질 별로 마찰에 의한 소음을 해석하는 스퀼 유한요소 해석 방법론을 제안하고 이를 실험 검증하고자 하였다. 회전운동 실험 장치를 통하여 각 재질 별 마찰곡선을 확인하였으며, 왕복운동 시험 장치에서 재질 별 마찰 소음을 계측하였다. 계측 된 마찰곡선을 특정 속도에서 선형화하여 마찰곡선 기울기 데이터를 FE Model에 적용하였다. 제안 된 해석 모델에서 발현 된 불안정 모드가 시험에서 발생한 스퀼 주파수와 유사함을 보였다.
