Abstract

In this study, to enhance the overall performance of a gantry machining center's crossbeam, static analysis identified critical load conditions (cutting forces, self-weight, and component loads). Dynamic analysis employed Yoshimura's method to establish joint dynamics models, obtaining modal parameters (natural frequencies, mode shapes, and vibration amplitudes). A hybrid optimization approach combining topology optimization and bionic design was implemented: topology optimization first determined optimal material distribution, followed by bio-inspired rib layout refinement inspired by turtle shell morphology. This methodology achieved balanced static-dynamic performance with lightweight design, integrating computational mechanics and biological structural advantages.
