In this article, the Lathe Bed of DL20-MST CNC machine tool is taken as the research object. The response surface method and optimization design of goal-driven are introduced. Combining the two methods, the size optimization design method of the Lathe Bed of NC machine tool is put forward based on the ANSYS. The design dimensions which play an important role in the static and dynamic performance of Bed are found through sensitivity analysis. And then, the goal-driven optimization design of the Lathe Bed is carried out based on the response surface method, searching for the optimal dimensions of Lathe Bed, realizing the lightweight design of the Lathe Bed of NC machine tool. In addition, the improvement on the performance of Lathe Bed after optimization is analyzed. The ideas and methods used in this paper offer a good reference for the design and production of the key parts of other similar machine tools, and have a great engineering application value. |
