Calculation of dynamic characteristics of spindle unit and multi-criteria selestion of their most rational Parameters
The paper presents the methodical approach to the calculation of dynamic characteristics of spindle unit and multi-criteria selection of their most rational parameters. On the example of spindle unit with belt drive of spindle unit with belt drive of the circular grinding machines was held the choice of parameters, using as the criteria values of natural frequencies and mode shape of spindle. Parameters boundary of spindle unit, meeting the requirements of its dynamic qualities throughout the operating frequency range were determined.
