摘要

在微連體理論之基礎下，本文主要在探討複合形狀寬滑塊軸承於使用非牛頓偶應力潤滑劑情況下之摩擦與流量性能。根據所得結果，若與使用傳統牛頓流體潤滑劑複合形狀滑塊軸承之情況比較，則非牛頓偶應力效應可以降低複合滑塊軸承之摩擦參數並減少所需供應流量。此種性能之改善，尤其在高偶應力參數值之情況下更為明顯。為能導引本研究之實務應用，本文亦提供數值實例以及計算之結果，有助於工程上之應用。

Based upon the micro-continuum theory, the frictional and flow-rate performances of wide composite slider bearings lubricated with non-Newtonian couple stress fluids are mainly concerned. Comparing with the Newtonian-lubricant composite slider-bearing case, the effects of non-Newtonian couple stresses provide a reduction in values of the friction parameter and the volume flow rate required. These improvements on bearing characteristics are more emphasized with increasing values of the couple stress parameter. A numerical example and the predicted results are also included for engineering application.
