Surface Roughness and Slip Velocity Efect on Magnetic Lubricated Porous Pivoted Slider Bearings

This paper describes the theoretical analysis of the surface roughness and slip velocity effect on magnetic fluid based porous-pivoted slider bearing. The bearing surface is defined by stochastic random variable with skewness, variance and non-zero mean. The concerned stochastically averaged Reynolds equation is solved numerically to get the pressure distribution. The expression for dimensionless centre of pressure is obtained in form of integrals. The value of centre of pressure is calculated and plotted numerically. It is observed that the value of centre of pressure depends on surface roughness, magnetic, slip and permeability parameters. It is concluded that slip and permeability parameters play a vital role for increasing the life of bearing system roughness.
