자동차 와이퍼 블레이드의 단면거동에 대한 분석

초록

As automotive industry become quieter, the interest in the wiper is increasing. The wiper system of a car is carried out the wiping of the windshield for securing a clear view. The most of complaints of wiper concern operation noise. The noise operation can be classified into three main categories namely, chattering, reversal vibration and squeal noise. In this paper, we focus on reversal vibration mainly occurred by reversal action. We use commercial software ANSYS for finite element analysis (FEA). The real behavior of wiper blade was observed by high speed camera (HSC). To reduce operation noise caused by reversal vibration, we use design of experiment (DOE) method for important variables such as friction coefficient, input force and damping coefficient.
