Description
  • This paper presents a thermo-mechanical model of spindles with rolling bearings. Thermal deformation due to spindle internal heat sources affects significantly properties (internal loads, stiffness) of rolling bearings and need to be considered in predictive models of spindles' dynamics. The structure of the transient model contains thermo-mechanical loops which update the model with respect to the instantaneous condition of the spindle. The predicted bearing properties are then used to estimate the variation of natural frequencies and dynamic stiffness of the spindle.
