Study on lightweight structural optimization design system for gantry machine tool

Abstract

In order to improve the efficiency and effectiveness of the lightweight design of the gantry machine tool, a lightweight structural optimization design system for the gantry machine tool was constructed. Serialized gantry machine tools were parametrically modeled, and a load model with multiple operating conditions was established. A twice optimization design method integrating zero-order optimization, parameter rounding, and structural re-optimization was proposed. Using the proposed method, a lightweight structural optimization design system for gantry machine tool with parametric design, lightweight design, and other functions was developed. The developed gantry machine tool lightweight structural optimization design system was applied to complete the lightweight structural optimization design of gantry frame of a certain gantry machine tool, so the structural parameters of the gantry frame were optimized. Although the maximum stress and the maximum deformation of the gantry frame increases within the allowable range, the experimental comparison before and after the optimization shows that the mass of the whole gantry frame is reduced by 9.24%, which is beneficial to save the manufacturing cost. The research results show that the constructed lightweight structural optimization design system of the gantry machine tool has high engineering practicality.

DMA2022：Vibration control of the rail grinding vehicle with abrasive belt based on structural optimization and lightweight design

“…JANG et al [28] developed a novel ultra-lightweight frame for a flatbed trailer, optimized the thicknesses of the member plates and the boundary shapes with the Taguchi method through computer aided engineering (CAE) software, improved frame bending and torsional stiffness, and reduced its mass by 24.5% compared to the original model. This structural optimization method is widely favored by many researchers in the lightweight design field [29][30][31][32]. However, the structure of the rail grinding vehicle determines its stability and grinding quality, thus leading to some limitations in optimizing the structure.…”
