本論文是以電漿放電奈米製造系統所生產的奈米煞車油作為實驗項目,並以氣壓推動之方式建立一套摩擦量測系統。此摩擦量測系統能夠提供不同的力量輸入以及不同速度變化。主要針對摩擦力、速度、加速度以及黏滯效應等摩擦性質進行一動態研究,訂定不同粒徑與材料的奈米煞車油,利用Load Cell來量測其摩擦力之變化,並以LVDT來記錄其位移之變化,在經由系統軟體LabVIEW來進行一整合性之動作,並且比較其不同實驗條件以及不同之實驗項目之下,進而分析其摩擦性質之結果,來瞭解其奈米顆粒對其煞車系統之影響關係。 由實驗結果得知,DOT-3煞車油中加入奈米顆粒確實能夠降低其摩擦力,對於時間停滯效應也能夠降低其摩擦,而在黏滯效應,除了減少初始摩擦力外,對於其摩擦震盪方面,也有明顯的緩和效果;另外在比較多組的實驗結果得知,其奈米顆粒的大小與材料為影響其摩擦力與趨勢的主因;未來方面,希望以更多奈米尺寸與材質,來建立一完整的資料庫,進行深入之研究。
This thesis is to build the measurement of friction force. The brake system uses nano oil acting by a pneumatic cylinder. The input parameters include forces and velocities. The measuring results include friction forces, velocities, accelerations, and stick-slip effects. Load cell and LVDT are used to measure friction force and position of brake cylinder, and compare the difference of friction properties under various nano particles oil. Results show the DOT-3 brake oil that adds nano particles decreasing the friction force. For a long stagnation time, the brake oil adds nano particles either decreasing friction forces or increasing the oscillations. The sizes and types of nano particles had a great effect on the friction forces of brake nano oil. In the future, more size and types of nano particles of brake oil can be tested in this field.
