The improvement of structure for high-speed electric spindle
The configuration of bearings and the choice of the ways of prestressing was analyzed, and build the parametric finite element model of high-speed electric spindle bearing-spindle system, using finite element analysis software's optimization design function, aim to improve spindle rigidity,by specifying parameters as design variables,state variables and objective function to establish analytical procedures, and the design variables as independent variables ,changing its value,iterative calculation until the minimum objective function value,state variables used to control the independent variable values through iterative process.The result indicated: after optimization of the spindle bearing span, the rigidity and the first-order natural frequency had the certain extent enhancement, thus has provided the rationale for the electric spindle structure's improvement.
