Abstract
The distortions of a thrust pad and its runner are analysed by solving the biharmonic equation of plate flexure by both elastic and thermal causes. The temperature and pressures are obtained from the simultaneous solution of the Reynolds and energy equations. The major similification is the assumption of constant temperature through the thickness of the oil film, though it varies in both the other directions. The equations are set up and their reduction to a form suitable for computing is described. Four modes of distortion are considered, pressure and thermal bending, direct compression and direct thermal expansion.Keywords
