Modeling of a deep-groove ball bearing with waviness ...

Jan 28, 2014· Jan 28, 2014· An approach for dynamic modeling of a deep-groove ball bearing with waviness defects in planar multibody system is presented. The deep-groove ball bearing is modeled by introducing a nonlinear force system that takes into account the contact elastic deformations between the ball elements and raceways. Hertzian contact theory is applied to calculate the elastic deflection …
