Article Preview

In order to improve the dynamic characteristics of crossbeam of heavy NC gantry moving boring & milling machine, the ribbed slab structure of beam were analyzed and optimized with the finite element analysis software, and the comprehensive optimization method of the number, size and layout of ribbed slab were putted forward based on the classification of ribbed slab structure. According to the result of the finite element analysis, the internal type and horizontal spacing of ribbed slab are optimized to get the best number, spacing, thickness and height of ribbed slab; Under the required intensity, stiffness and stability conditions materials are distributed reasonably to reduce beam weight which make little deformation and the uniform stress distribution. The comprehensive optimization method study has reference value for ribbed slab structure design.
