當兩機械元件受力後互相接觸且有相對運動時,必須考慮兩表面間之接觸性質,如磨潤、變形與接觸方式等現象。本實驗透過多功能磨潤試驗機來模擬接觸元件運動情形,目的在分析點接觸元件在不同正向力、側向力與轉速下接觸時的溫度、摩擦係數與電阻,觀察在不同控制參數下的變化差異。而目前,對精密元件的界面研究中大多只有探討正向力的影響,然而在機台運作時,元件常承受部分側向力。因此需了解側向力對機械元件作動時的磨潤性能影響,進而改善與提升品質。 經由實驗所得之數據結合灰關聯與田口方法分析關聯度,由因子反應圖得知:正向負荷的參數是影響結果的最大因素,正向負荷越大溫度會隨之越高;而側向負荷的加入,對溫度的影響不大,但摩擦力有減少的跡象。本研究成果亦證實灰色田口法可比對出磨潤試驗的關聯度。
When two mechanical elements by force after contact with each other and relative motion, we must consider the nature of the contact between the two surfaces, such as tribological deformation and contact phenomena. Experimental through multifunction tribological testing machine to simulate the contact element motion conditions, purposes in the analysis of the point contact element in contact under different forward force, lateral force and the rotational speed when the temperature, the friction coefficient and the resistance observed in the different control parameters. change differences. At present, on the interface of the precision components mostly only explore the positive force of the impact, however, the operation of the machine, the part of the lateral force components are frequently subjected. Therefore need to understand the lateral force on the tribological performance of mechanical components for moving, and thus improve the quality and enhance. Combined with gray relational data obtained through the experiment with the Taguchi method to analyze the correlation degree, learned by a factor Reaction: the positive load the parameters is the biggest factor to affect the outcome, the positive load the greater the higher the temperature will follow; lateral load to join, has little effect on the temperature, but the friction is the sign of abating. The results of this study also confirmed the grey Taguchi method comparable on the tribological tests associated..
