Dynamic force transmissibility of flywheel rotor systems supported by angular contact ball bearings considering clearance fit

This study investigates the dynamic force transmissibility (DFT) of angular contact ball bearings (ACBB) supported flywheel rotor systems (FRS) considering the clearance fit. By introducing the influences of combined load and contact angle variation in the Jones formula, the internal load distribution and nonlinear stiffness of ACBBs are accurately solved. The rigid inner/outer ring contact model is adopted to characterize the clearance fit...
