【摘要】 本文选取具有应力过量现象的Oldroyd流体作为润滑剂模型,从理论上研究滑动轴承的润滑问题。选取无量纲化的松弛时间为摄动参数,用摄动法求解,发现弹性效应是增大承载能力和摩阻。更多还原

【Abstract】 Consideration is given to the flow of an Oldroyd fluid in the slider bearing con figuration. The problem is solved by perturbation method, where the relaxation time is chosen as the perturbation parameter. It is found that the effects of elasticity are it. increase the loading capacity and the drag.更多还原
