Abstract

The present study conducted a parameter effect analysis of low-frequency squeal noise using a numerical simulation. The finite element program ABAQUS was used to calculate the dynamic instability based on a complex eigenvalue analysis. A total of five parameters, including the chassis, wear, piston, material property, and contact condition, were selected to identify the factor effects on a low-frequency squeal noise between 2.5 and 3.1 kHz. The present study found the dominant level of each factor through an analysis of the means in the context of the experiment design.

본 연구에서는 구조해석 시뮬레이션을 통해 저주파 스퀼을 유발하는 여러 요소를 분석하였다. 해석을 위한 프로그램은 ABAQUS 를 사용하였으며 동적 불안정성을 판명하기 위한 방법으로는 복소 고유치 해석을 채택하였다. 스퀼 유발 요소와 관련된 핵심적인 5 가지 인자를 선정하였고 각각 3 수준으로 분류하였다. 이를 분석하기 위해 실험계획법을 적용하였고, 파라미터 영향도 분석에는 평균분석을 적용하였다. 이을 통해 영향도가 큰 인자를 선별하였고 타당한 해석 기법 및 파라미터 영향분석을 수행하였다.
