세탁기 모터 마운팅 고무의 내구성 평가 및 가속수명시험 연구

Abstract

The mount rubber of a washing machine receives the repeated fatigue loadings during laundering. Although the mount rubber is designed statically safely, it often happens fatigue failure. Therefore it requires the safe design for fatigue and needs the prediction of quantitative fatigue life. This paper discusses the accelerated life tests were carried out to predict the useful life of IIR mount rubber components of washing machine. Accelerated life test were performed using specimens with different levels of temperature condition and various hardness. The lifetime model based on Arrhenius model is proposed, and the mount rubber's lifetime distribution are statistically estimated using MINITAB program.
