PERFORMANCE OF A MAGNETIC FLUID BASED LONGITUDINALLY ROUGH PLANE SLIDER BEARING

<p>The analysis on the performance of a longitudinally rough plane slider bearing under the presence of<br>magnetic fluid is presented. The magnetic field is oblique to the stator and the bearing surfaces are assumed to be<br>longitudinally rough. The roughness of the bearing surfaces is characterized by a stochastically random variable<br>with non-zero mean, variance and skewness. The concerned Reynolds equation is averaged with respect to the<br>random roughness parameters. This equation is solved with appropriate boundary conditions to obtain the expression<br>for pressure distribution which is further used to calculate the load carrying capacity. The results are presented<br>graphically. It is seen that the load carrying capacity increases due to the magnetic fluid lubricant. It is also observed<br>that the roughness affects the bearing performance adversely. The study reveals that the negative effect of roughness<br>can be minimized by the positive effect of magnetization.</p> <p>
