由於摩擦面相對運動導致摩擦之生成熱，摩擦過程所累積的熱能造成溫度上升，引起摩擦表面形貌之改變，同時也導致材料進行相變化，這些因素使得摩擦現象變的複雜及難以預測，而摩擦面溫度的量測是不易進行的。
本研究中使用自行設計方式之石墨碳刷感測器，進行摩擦表面溫度量測，並量測在固定負荷及轉速下的磨耗率，再加以分析碳刷的摩擦係數之關係：最終之目的是要建立碳刷感測器在摩擦機構上量測摩擦表面的真實溫度。同時利用資料擷取卡及LabVIEW來對類比訊號作資料處理，此資料來進行摩擦溫度與摩擦面形貌之關係研究。

Since relative motion of friction surface would generate the heat, the temperature will rise by accumulative heat in friction process and result in change on appearance of friction surface. These factors make friction phenomenon complicated and hard to predict. Meanwhile, the measurement of temperature on friction surface is not easy.
The research adopted the self-designed graphite-carbon brush sensor to measure the temperature on friction surface and also the wear rate under fixed loading and rotation speed to analyze the relationship among friction coefficient of graphite-carbon brushes. The final goal is to obtain the actual temperatures on friction surfaces measured from applications of graphite-carbon brushes. The data collection card and LavVIEW are also used to process analog signal and study the relationship between friction temperature and appearance of friction surface through the data.
