中文摘要 | 本文考慮兩個金屬面,一為鑄鐵,另一為鋼,以實驗探討摩擦引致之振動。本文 以銷盤接觸裝置作實驗。滑動面為乾燥或潤滑狀態,在高滑動速度下,檢驗接觸負荷對摩擦 與振動之函數關係。結果顯示在乾燥光滑盤與銷滑動接觸時,有四個摩擦特性區域,當負荷 超過一臨界值時,自激振動發生。當同樣接觸面以潤滑油潤滑時,由於潤滑油之黏性效果, 使摩擦較低且抑制了系統之劇烈振動。 |
英文摘要 | The friction-induced vibration between two metallic surfaces, one cast iron and the other steel, was experimentally investigated in this paper. The experiment works were conducted using a pin-on-disk machine with the contact surfaces either under dry or in lubricated conditions. The functional dependence of friction and vibration on the applied normal load in the high sliding contact was examined. The results show that four friction regimes are encountered during load evolution in the case of the smooth disk in dry sliding contact with the pin, and a self-excited vibration is observed as the applied load exceeds a critical value. When the same contact surfaces are lubricated with oil lubricant, the friction is lower and the severe vibration of the loading system is inhibited because of the strong viscous effect of the oil lubricant. |
