Static analysis of multi-support spindle shafts with nonlinear elastic bearings
Bulletin of the National Technical University «KhPI» Series: Dynamics and Strength of Machines, 2021 In this paper a mathematical model and computational tool are developed for the static analysis of multi-bearing spindle shafts with nonlinear elastic supports. Based on the Timoshenko beam theory a resolving system of equations is obtained that takes into account the nonlinear dependence of the bearing stiffness on the reaction forces acting upon them.
