摘要

本文从理论上研究了不同的多孔结构对多孔表面弯曲的上板以铁磁流体为润滑剂接近不透水的平坦下板时所形成的挤压膜的影响。本文考虑了Kozeny - Carman(球状模型)和Irmay(毛细裂隙模型)给出的两种多孔结构。得到了倾斜于下板的外磁场作用下的压力和承载能力表达式。结果表明,随磁化强度的增加,两种情况下的负载能力均有所增加。在Kozeny - Carman给出的凹板和多孔结构的情况下,载荷能力也有很大的提高。Kozeny - Carman给出的多孔结构的承载能力更大。

Squeeze Film Based on Ferrofluid in Curved Porous Circular Plates with Various Porous Structure
This paper theoretically studied the effects of various porous structure on the action of the squeeze film formed when a curved upper plate with porous facing approached an impermeable and flat lower plate using ferrofluid as lubricant. Two porous structures given by Kozeny - Carman( a globular sphere model ) and Irmay ( a capillary fissures model ) are considered for the study. Expressions are obtained for pressure and load capacity under an external magnetic field oblique the lower plate. It is found that the load capacity is increased in both the cases with the increase of magnetization. It is also found that the load capacity increased substantially in the case of concave plates and in the case of porous structure given by Kozeny - Carman. The load capacity is more for the porous structure given by Kozeny – Carman.
