Abstract
The hydrodynamic bearing consists of six pads these pads have the ability to tilt
about the clamping edge. Reynolds equation (2D) for dynamically loaded was used to find
the generated pressure value throughout the mobility method and the finite difference
method. The effects of many parameters of bearing were studied in this paper such as length
to diameter ratios, power loss, oil flow rate, Sommerfeld number, load number, friction
coefficient and by using the “Ansys program” for stress and strain analysis over the pad
surface (white metal), to select the best position location for adjustable pads mechanism
from leading edge angle to trailing edge angle of pad central angle (PCA=55°) by taking
nine different positions. The best angle for the adjusting member was found about (41.25o)
after leading angle of the pad, the adjusting member in the maximum pressure region gave
minimum radial displacement (elastic deformation) values.
