The varying compliance (VC) vibration directly reflects the oscillation intensity of a rolling bearing, and it can be fully revealed in VC resonance. Moreover, we define bearing as information this paper. Besides element number rotor eccentricity is also an inevitable influencing factor for vibration. This paper focuses on resonance characteristics ball system. An analytical model established, responses system are calculated large speed range with consideration different numbers...
This paper investigates the nonlinear characteristics of varying compliance contact resonance in a rotor–bearing system and takes into consideration Hertzian deformation internal radial clearance. We created an experimental rig rigid rotor supported by rolling element bearings. In course rotational speed run up down, frequency–amplitude curves vibrations were observed during experiments using different loads compared with results our numerical simulations. The indicate that vertical...
The nonlinear dynamic behaviors of dual-rotor-bearing systems with looseness and rub–impact faults are discussed in this paper. system coupling is established by the finite element method. component mode synthesis (CMS) proper orthogonal decomposition (POD) methods introduced. CMS POD used to reduce original rotor model, efficiency order reduction method verified comparing reduced systems. frequency spectrum amplitude–frequency studied. results can provide qualitative guidance structural...
