  • BEARINX -online Spindle Calculation - Schaeffler Group

    In this paper we proposed several optimization models for spindle-bearing systems. The goal is to find out the position of the bearings, the diameters of the spindle (different diameters for several segments of the spindle) in order to maximize dynamic stiffness (minimize receptance), i.e. the diminishing of the vibrations. Some constraints are …
