Integrated "CAE" strategies for the design of machine tool spindle-bearingsystems

This paper adopts both static and dynamic analyses to examine the necessary integrated procedures for the design of spindle-bearing systems, with mode ling and analysis of these systems being based on the finite element method . The study further addresses the sub-structure procedures and the applicat ion of a commercial package dynamic solver. Within this study, the effects of design parameters on static and dynamic performance of spindle-bearing s ystems are analyzed in order to establish the requirement for design modifi cations, and the paper proposes a number of examples, along with a set of g uidelines for the design of machine tool spindles.
