Numerical Simulation of Frictional Dissipation in the Dislocated Single Floating Ring Bearing

Abstract

The frictional dissipation in the dislocated single floating ring bearing is simulated by boundary element method (BEM). The advantage of BEM is that it can reduce the numerical simulation error and increase the numerical efficiency. The numerical results indicate that the total frictional dissipation decreases with the increases of the floating ring’s velocity and never change when the radius of the floating ring Rf=0.4. The evolution of total frictional dissipation is similar with the bearing’s frictional dissipation.
