[Abstract]:In order to solve the problem that the printing platform of gantry 3D printer is fixed and the printing space is limited, based on the principle of describing 3D space with three parameters of 蟻, theta and z in cylindrical coordinate system, a rotating motion is designed innovatively. A three-degree-of-freedom cantilever 3D printer that moves horizontally and up and down. Through the structural analysis and force analysis of the machinery above the base, the analysis model of the rotating transmission device is simplified. The static analysis and modal analysis of the simplified rotating transmission device are carried out by using the finite element software ANSYS Workbench. On the basis of static analysis and modal analysis, according to the lightweight design requirements, the key dimensions of the carrier of the reducer are optimized by using the response surface optimization tool of ANSYS. The optimization results show that the response surface optimization method can well complete the multi-objective optimization design and realize the lightweight of the whole machine.
