采用Jenkins模型，研究了滑动速度和材料常数对磁流体滑动轴承性能的影响。得到的表达式的压力，负载能力，滑块上的摩擦，摩擦系数和压力中心的位置。滑移参数的增加导致承载能力和摩擦力的降低，摩擦系数增加，而压力中心没有改变太多。随着材料常数的增加，承载能力降低，摩擦和摩擦系数增加，压力中心的位置稍微向轴承的入口移动。
The effects of slip velocity and the material constant in a porous inclined slider bearing lubricated with a ferrofluid were theoretically studied by using Jenkins model. Expressions were obtained for pressure, load capacity, friction on the slider, coefficient of friction and position of the centre of pressure. The increase in slip parameter caused decrease in load capacity as well as friction and increase in the coefficient of friction without altering the centre of pressure much. As the material constant increased, the load capacity decreased, friction and coefficient of friction increased and the position of the centre of pressure shifted slightly towards the inlet of the bearing.
