| Abstract | ||
| This work is a theoretical study of the performance of the hydrodynamic bearing having three pads ( parabola surface shape ) and this is compared with the performance of three circular shape pads . Reynolds equation is solved numerically using finite differences technique, A computer programe is build used the (MATLAB).The relationship between external load (W) and the pad tail displacement (g)is proportional, and also between (H) and (g) ، while the relationship between (Q) and (g) and between (Ф) and (g) are inverse proportional . The results of this research show that the pads tail displacement has a greater effect on this bearing performance (parabola shape) , than the tilt angle (α) on the bearing performance comparative with (circular shape). | ||
