Abstract
The aim of this article is to carry out analysis to enhance the performance of the ferro fluid lubricated porous step bearing. The porous coating is assorted to the lower flat impermeable surface. A step is there in upper surface which approaching to lower surface. This study considered that magnetic field is flexible and oblique to the lower surface. By considering Jenkins Model, expressions for pressure and load capacity are obtained. The non-dimensional load capacity is also calculated for various parameters. Based on results, it is observed that load capacity increases if suitable step size is considered. Also, comparison between R. E. Rosensweig Model and Jenkins Model is carried out. Finally, it is advised to design a porous step bearing, one should consider Jenkins Model over R. E. Rosensweig Model.
本文的目的是对提高铁流体润滑多孔台阶轴承的性能进行分析。将多孔涂层组合到下平面不透水表面。在上表面有一个台阶向下表面靠近。本研究认为磁场是柔性的，并向下表面倾斜。考虑Jenkins模型，得到了压力和承载能力的表达式。计算了各种参数下的无量纲承载能力。结果表明，如果考虑适当的步长，则负载能力增加。并对R. E. Rosensweig模型和Jenkins模型进行了比较。最后，建议设计多孔阶梯轴承，应考虑Jenkins模型而不是r.e. Rosensweig模型。
