Frame Structure Optimization Method Based on 3D Printing

Abstract

The invention disclosures a frame structure optimization method based on 3D printing, comprising following steps: a. inputting the information of force and material property of frame according to design requirement, and building an initial frame model by adopting generative design; b. conducting area reduction optimization for the initial frame model by using an edge contraction algorithm based on quadric error as metric cost, a simplification frame model is obtained; c. arranging point set in cavity of the simplification frame model, connecting each point in the point set, and calculating and retaining the most efficient point of distribution mode and connection mode in the point set based on a multi-objective optimization algorithm, deleting extra points, an optimization frame model is obtained; d. inputting tube radius, transforming the structure in the optimization frame model from the line to the body to obtain 3D printing model of the frame.
