A comprehensive review of modeling techniques for double-row tapered roller bearings

Double-Row Tapered Roller Bearings (DTRBs) possess notable advantages, including large load-carrying capacity, long service life, and the ability to withstand combined radial and axial loads, as well as bending moments. DTRBs are widely used in mechanical equipment and machinery, such as precision machine tools, automotive vehicles, railway vehicles, and wind turbines. The static and dynamic modeling of DTRBs plays a pivotal role in analyzing bearing tribological behavior and mechanical system performance, as well as in design and optimization. Over the past decades, extensive research has focused on DTRBs modeling and analysis to elucidate their tribological behavior and vibration mechanisms, thereby improving design and application. However, no comprehensive review has yet summarized the research progress on this topic. To fill this gap, this paper conducts a state-of-the-art review on DTRBs modeling and analysis, including the processes and differences in static modeling using traditional, multibody, and finite element methods, the techniques and implementation of dynamic modeling, and the current research progress in this field. This review also provides recommendations for future research, aiming to facilitate further development of DTRBs modeling and analysis.
