Finite element model updating of a geared rotor system using particle swarm optimization for condition monitoring

In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data,  iezoel...

The Effect of Damping and Stiffness of Bearing on the Natural Frequencies of Rotor-bearing System

In this paper, the effectiveness of stiffness and damping of bearing is investigated on the natural frequencies of the rotor-bearing system. The rotor-bearing system consists of a shaft, two bearings and a disk between two bearings. Parallel spring-damper in horizental and vertical directions is considered for modeling the stiffness and damping of bearings. The gyroscopic effect is also conside...

Dynamic Analysis of a Rotor-Journal Bearing System for Twin Rotary Compressors

A rotor-journal bearing system for a twin rotary compressor has been nlliDerically analyzed to estimate the reliability and to optimize the bearing design. For rotary compressors, large dynamic loads act on the rotor. They are unbalanced forces due to eccentric rotation parts and gas forces induced by the difference in pressure between compression and suction gases. In such a case, the rotor-jo...
