Lightweight optimization design of horizontal double-sided combined machine tool bed based on ANSys workbench

In this paper, the bed mechanism of the horizontal double-sided combined machine tool is taken as the research target. Firstly, the static and dynamic analysis methods are used to simulate the working state. The equivalent stress and deformation distribution are calculated by static analysis of the bed to judge whether it meets the strength and stiffness requirements or not. Through the modal analysis of the machine bed, the first six natural frequencies and modal mode are obtained to study the dynamic characteristics of the bed working state. Furthermore, the response surface optimization module (Response Surface Optimization) included in the optimization design toolbox of ANSYS Workbench software is used to lighten and optimize the bed structure. By comparing the optimization results before and after, the bed quality of the horizontal double-sided combined machine tool is reduced by 3.36% under the condition that the rigidity of the machine tool is improved or not reduced, and the lightweight optimization design of the horizontal double-sided combined machine tool is realized. © 2019 Editura Politechnica.
