Optimization Design of Lather-beds Based on FEA

摘要

The lathe-bed is a critically important part of a lathe, on which the performance of a machine tool depends largely. The optimization of a lathe-bed is hence an important issue in machine tool design. In this paper, we present three-dimensional modeling and finite element analysis methods for the optimization design of CNC lathes. We use PRO/E and PRO/MECHANICA to build three-dimensional modeling and to optimize the structure of lathe-beds. The final modal analysis shows that the presented optimal design is feasible and can produce a better structural performance.
