摘要

汽車雨刷膠條與擋風玻璃間之摩擦及磨耗可能造成刷拭效果不佳並產生振動及噪音問題，因而影響駕駛及乘客之視野及舒適性，甚至危及駕駛安全。因此，雨刷膠條在玻璃上之磨潤行為是一重要研究課題。本研究設計並製作Pin-on-disc式測試機台，並且探討雨刷膠條與玻璃表面間之磨擦現象。實驗參數包括材質、負荷、轉速、及乾濕條件等。研究結果顯示：摩擦係數隨膠條負載之增加而降低，而在高速下之摩擦係數較低速時為高。此外，並發現於天然橡膠中添加合成氣丁橡膠橡膠具有減低摩擦係數之效果，這在文獻上鮮被探討。本研究結果在雨刷結構動態設計上可提供參數設計及材料選別之參考。

The friction and wear between automobile wiper blade and windshield glass may result in poor wiping, and have potential to generate unwanted noise and vibration level. This leads to poor visibility, comfortability, and it may even creates a driving safety hazard. As a result, the study of tribological behaviors of wiper blade on glass is significant. In the present study, a pin-on disk testing device was designed and manufactured, and the friction of wiper blades on glass surface were investigated. The experimental parameters included material, loading, wiping speed, and dry/wet wiping conditions. The results show that the friction coefficient decreases with the increase of normal force per unit length. And higher wiping speed results in higher friction coefficient. Besides, it was observed that adding poly chloroprene rubber to natural rubber can significantly reduce the friction coefficient of wiper blades, which is barely studied in the literature. The results are expected to provide a reference for the parameter design and materials selection in the dynamic design of wiper structures.
