基于UG建模的球类零件轻量化结构设计与力学分析探究

Lightweight structure design and mechanical analysis of spheroid parts based on additive manufacturing

以球体类零件的结构轻量化设计为主要研究对象,利用UG软件进行轻量化零件的实体建模,在保持相同外观、尺寸条件下,实现其内部结构从实体结构设计变更为三角形筋肋、O形筋肋和网格状筋肋的不同结构。对不同内部结构的球体零件和实心零件分别利用ANSYS软件进行静力学仿真分析,并输出应力、应变云图,以最接近实心零件的强度为判据,证明网格状结构最佳。

In this paper,the structural light-weight design of spherical parts as the main research object,using UG software for light-weight parts entity modeling,in the same appearance,the same size,the realization of its internal structure from the solid structure design change to triangle rib,0 rib and mesh rib of different structures.The static simulat ion analysis of sphere parts and solid parts with different internal structures is carried out by ANSYS software,and the stress and strain nephogram is output.The strength of the closest solid part is taken as the criterion to prove that the mesh structure is the best.
