On the basis of hydrodynamic theory of lubrication, the components of the resultant film force acting on the journal in the infinitely wide bearing can be expressed as functions of x, y, x^^. and y^^., where x and y are the rectangular co-ordinates of the displacement of the journal center. By expanding these functions into the power series in x, y, x^^. and Y^^., the film elasticity and film damping for small displacements from the position of static equilibrium are derived. In the process of the derivation, the influence of the variation of the film extent due to the motion of the journal center is taken into account in an approximate manner. It is shown that the cross coupling terms of both film elasticity and film damping are not small in comparison with the other terms, and that they reach their minimum values at some values of the Sommerfeld variable.
