  • The dynamic characterisation of rolling-element bearings : dissertation
    Razpotnik, Matej
    The transmission of vibration through rolling-element bearings is a major topic of interest with respect to the modern rotating machinery. Due to the complex contact conditions the bearing modelling ... as part of a wider system primarily remains on the analytical level. This work discusses in the first part the adequacy of current analytical bearing models by comparing their load-displacement characteristics. Afterwards the bottom-up investigation of a system is presented. Based on precisely known dynamic properties of all integral parts but bearings we asses the dynamic bearing model. The next part of this work describes the numerical issues that appears when calculating the time response of a system containing rolling-element bearings. A derivation of smooth contact-state transition model is presented that ensures faster and stable integration procedure. In the last part the statically indeterminate system containing rolling-element bearings is investigated. More unknowns than available equations require a new numerical approach to calculate a resulting equilibrium of the system.
