  • Research on a Numerical Calculation for Ball Bearings ...

    2021-1-4 · For example, the numerical analysis on the double-decker rolling bearing is studied , the mechanical model of a “Z-” type and “I-” type double-decker ball bearing is established [22, 23]. In the above studies, the traditional Newton–Raphson algorithm is applied to most of the numerical model solutions for ball bearings.
