【 摘 要 】

In order to explore a new way to improve the static and dynamic performance and lightweight of machine tool, the machine tool worktable filled with basalt fiber polymer concrete (BFPC) is designed, which take a worktable of vertical machining center as the research prototype and meet the stiffness and light weight as the constraint conditions. The static, dynamic performance weight of prototype structural columns are simulated and analyzed by using Workbench software. Taking the width and height of rectangular hole of worktable filled with BFPC as design variable, taking the maximum stress and maximum strain of prototype worktable as constraint conditions, taking maximum of the first three order natural frequency and the lightest mass of worktable filled with BFPC as object function, the sensitivity histogram and response surface of each parameter are acquired by using optimization design. Then the best width and height of rectangular hole of worktable filled with BFPC are finally determined. The static and dynamic performance, quality and the first three order natural frequencies of the optimized filling structure are compared with the prototype structure. Finally we can know that the static, dynamic performance of the machine tool can be improved by using worktable filled with BFPC and ensuring light weight.
