| 摘 要： | 运用计算机代数系统，先取四参数Oldroyd流体作为斜面滑块轴承的润滑剂，吧无量纲松驰时间为振动参数，用正则摄动求解润滑问题的一阶解和二阶解，得出了一阶解的弹性效应对轴承润滑特性的影响是增大承载力和减小摩阻的结论，类似的结论在二阶解的弹性效应中也成立。

| Abstract: | In this paper, consideration is given to the lubricate of a four-parameter Old-rovd fluid in the slider bearing. The problem is solved by computer algebra syst(?)m and perturbation method, where the relexation time is chosen as the perturbation parameter. It is found that the effects of elasticity are increase the loading capacity and decrease the friction. |
