The Dynamics of Tapered-roller Bearings – A Bottom-up Validation Study

Rolling-element bearings are one of the most important elements when predicting noise rotating machinery. As a major connecting point between and non-rotating parts, their dynamic properties have to be accurately known. In this investigation we present bottom-up approach characterising dynamics rolling-element bearing. A special test device was designed built assess quality well-established analytical modelling Lim Singh. Two types were tested, i.e., ball tapered-roller types. The observed by investigating frequency-response functions. addition, as well scenarios checked. It shown that bearing model adequately predicts system’s response, whereas requires modifications. These results further confirmed with quasi-static load-displacement numerical evaluation, where full finite-element serves reference.
