20.500.12556/RUL-148931 The dynamics of tapered-roller bearings – a bottom-up validation study Dinamska karakterizacija stožčastih ležajev – validacija od spodaj-navzgor Rolling-element bearings are one of the most important elements when predicting the noise of rotating machinery. As a major connecting point between the rotating and non-rotating parts, their dynamic properties have to be accurately known. In this investigation we present a bottom-up approach to characterising the dynamics of the rolling-element bearing. A special test device was designed and built to assess the quality of the well-established analytical modelling approach of Lim and Singh. Two types of bearings were tested, i.e., the ball and tapered-roller types. The dynamic properties were observed by investigating the frequency-response functions. In addition, non-rotating as well as rotating test scenarios were checked. It was shown that the ball bearing model adequately predicts the system’s response, whereas the tapered-roller bearing model requires modifications. These results were further confirmed with a quasi-static load-displacement numerical evaluation, where a full finite-element model serves as the reference. dynamic bearing model tapered-roller bearing bearing stiffness matrix vibration transmission dinamski model ležaja stožčasti ležaj kroglični ležaj togostna matrika ležajev prenos vibracij študija od spodaj-navzgor true false true Angleški jezik Slovenski jezik Članek v reviji 2023-09-01 08:31:31 2023-09-01 08:31:33 2025-05-05 13:47:21 0000-00-00 00:00:00 2023 0 0 Str. 289-298 no. 7/8 Vol. 69 Jul./Aug. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.822.7 0039-2480 10.5545/sv-jme.2023.592 159139331 Razpotnik_..._-The_dynamics_of_tapered-roller_bearings_–_a_bottom-up_validation_study.pdf Razpotnik_..._-The_dynamics_of_tapered-roller_bearings_–_a_bottom-up_validation_study.pdf 1 5B270166BFF93613BAE6AE4C85F6DFFD 6df24f2c5bee802a97b63676722b82e25252e21556b9d6bc6d0e32c54279cd7b 8c8e3e0b-4891-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173298 https://www.sv-jme.eu/sl/article/the-dynamics-of-tapered-roller-bearings-a-bottom-up-validation-study/ 1 36bd362d-4891-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173297 Fakulteta za strojništvo 0 0 0
