Simulation of Rolling Bearing Performance within Models of Complete Structures

摘要

Simulation of the behavior of rolling bearings requires models on vastly different physical scales. The machinery in which the bearing is mounted determines the loads, while the finest micro-structural constituents in the grains of the bearing material determines the fatigue life of the bearing. The paper describes the analysis with a complete set of models. On the macro scale a gearbox is modeled with housing, shafts, gears, and bearings. On the next level, a detailed simulation of one bearing is made, including motion of, and forces between, internal components. Finally, a roller to raceway contact is examined with respect to surface roughness, and its effect on life.
