Abstract

Abstract: Aiming at lattice design of the integration of function and structure， a design method for strengthening lattice structure nodes was proposed based on the analysis results of beam model. Taking the gear as the carrier whose web was filled with lattice structure， a vibration detection platform was built to verify the functional performance of the lattice structures. Experimental results show that compared with the lattice structure with the same mass， the amplitude of the functional lattice structure decreases by 20.90% and the loading capacity increases by 30.00%.

Key words: 3D printing, lattice, beam model simulation, integration of function and structure
