This research aims to derive generalized equations of motion and propose a generalized analytical model for a sloped rolling-type isolation bearing in which the two V-shaped surfaces in contact with one cylindrical roller are designed with arbitrary sloping angles. The influences arising from the neglect of higher order terms of sloping angles and vertical excitations in the derivation of the horizontal acceleration prediction of the isolation bearing are numerically examined. It is indicated that the effect of higher order terms of sloping angles on the prediction accuracy is very limited. However, if the acceleration excitation possesses a considerable vertical component, adopting the exact generalized equations of motion, rather than the simplified ones, can obtain more desirable and conservative analysis results for the isolation bearing. |
