In this paper, a theoretical analysis of the effects of magnetic field and couple stress on the squeeze film lubrication characteristics between rough triangular plates is presented. A generalized form of surface roughness is considered, and the modified average Reynolds equation is derived based onstochastic random variable with non-zero mean, variance and skewness with Magnetic field and couple stress fluid. Closed form solution is derived for squeeze film pressure, load carrying capacity and squeeze film time. Our result shows that there is a significant increase for pressure, load carrying capacity and squeeze film time due to magnetic field and couple stress lubricant, while these non-dimensional parameters decreases due to the standard deviation. It is noted that negatively skewed roughness increases the pressure, load carrying and squeezing time.
