چکیده
A method for calculating amplitudes and constructing frequency characteristics of forced self-excited vibrations a rotor-fluid-foundation system on rolling bearings with non-linear characteristic based the complex harmonic balance has been developed. Non-linear equations motion are derived, analytical methods their solution presented. Frequencies fundamental ultra-harmonic resonances determined. The intervals between self-oscillation frequencies estimated. dependence amount fluid in rotor cavity, mass foundation, linear imbalance, value stiffness coefficient, damping coefficient is shown.

Multi-objective design optimisation of rolling bearings using genetic algorithms
The design of rolling bearings has to satisfy various constraints, e.g. the geometrical, kinematics and the strength, while delivering excellent performance, long life and high reliability. This invokes the need of an optimal design methodology to achieve these objectives collectively, i.e. the multi-objective optimisation. In this paper, three primary objectives for a rolling bearing, namely, ...
متن کاملSimulation of Rolling Element Bearings
Rolling bearings are high precision, low cost machine elements, used in all kinds of rotating machinery. Simulations of rolling bearings bring increased understanding of their dynamic behaviour, and shortens product development time. A rolling bearing simulation model called BEAST (BEAring Simulation Tool), has been developed by SKF. Due to the high demands on contact geometry description and c...
متن کاملElectrostatic wear monitoring of rolling element bearings
Research and development work at the University of Southampton using an electrostatic condition monitoring system developed by Smiths Aerospace Information Systems has shown that electrostatic charge signals can be used to detect the onset of wear in lubricated tribo-contacts. Preliminary investigations have already demonstrated the viability of this system when tested on a laboratory-based pin...

متن کاملParametrically Excited Vibration in Rolling Element Bearings
A defect-free rolling element bearing has a varying stiffness. The variation of stiffness depends on number of rolling elements, their configuration and cage frequency. The time-varying characteristics of the stiffness results in a parametric excitation. This may lead to instability which is manifested as high vibration levels. An FEM simulation is performed to evaluate stiffness in each config...
