Abstract：the rotor dynamic performance of overhung rotor supported on floating ring bearings (FRBs). The Reynolds equation and bushing motive regulation of FRB are established. The forces of two oil films are calculated using 4-node isoperimetric h-version refining FEA method by Galerkin approximation. The equivalent stiffness and damping coefficients of the FRB are obtained combining with the dynamic equations. This paper also presents the rotodynamic simulations of the critical speed, unbalance response by using the commercial software Ansys 12.1. By contrast with test results, this proposed model of overhung rotor system is of good validity and practicability in design work for future.
