摘要：The article presents an FEM model of the spindle system, in which angular contact ball bearings with activepreload control are used. This model allowed determining the frequency and form of natural vibrations of the sys-tem. The model was prepared using the Abaqus programming environment. Various bearing preload states wereadopted during the tests. It was shown that the spindle system is sensitive to the changes in the stiffness of bear-ing supports. The tests conducted using models were then verified on a real stand. First of all, using the externalexcitation from an electromagnetic exciter, the frequency range of resonance vibrations of the spindle system wasdetermined. Then, the amplitude - frequency characteristics of the tested spindle were determined at various bear-ing preload values. A general operation scheme of the control system for the active change of the preload value ofthe angular contact ball bearings during the work of the spindle system was proposed.
