論 文 摘 要

本研究團隊過去已成功發展摩擦帶電機制成為動態監控金屬磨潤特性的新方法，並且發現不管是就靈敏性或判別性之考量，上述此種新方法均優於傳統以摩擦係數監控的方式，但卻因導電特性之限制而只侷限在導體對導體材料之配對。因此進一步發展以接觸電阻動態監控金屬對金屬於空氣中磨潤特性及磨耗機制，並已成功判斷界面間化學反應物。
本研究擬進一步利用上述的實驗設備與量測技術，探討垂直方向剛性對摩擦界面間磨潤性質之影響。於不同彈簧k值與各種基礎油品條件下，根據動態量測摩擦界面間接觸電阻及摩擦係數，並同時量測磨耗損失量及以SEM觀察微米級材料轉移現象，進行一系列垂直方向剛性對磨潤性質影響之動態監控研究。未來將可進一步根據本研究成果而詳細探討垂直方向剛性對機台振動的影響。

ABSTRACT

The novel method of using continuous tribo-electrification variations to monitor the dynamic tribological properties between metal films has been applied successfully by the authors. The method was shown to produce clear and strong signals, superior to monitoring continuous friction coefficient variations. However, the above method was only shown to be suitable for the tested metal pairs that were studied. Therefore, the authors further investigated the method of using electrical contact resistance variations for monitoring the tribological properties, the wear mechanisms and the chemical reactions between the interfaces of metal pairs.
The study was based on the above experimental equipments and measure technology to investigate the effect of normal stiffness on the tribological properties between the interfaces. The values of k and bases oil
were selected as the main parameter. According to the continuous variations of electrical contact resistance and friction coefficient, with Wear loss and SEM of observations on the micro wear structures and of material transfer, study in series of normal stiffness on the tribological properties can be conducted. Furthermore, the experimental results can also be used to clarify the study of machine vibration in the future.
