The invention belongs to the technical field of aircraft component design, and particularly relates to a layering design method of an electron beam fuse deposition forming structure. The method comprises the steps that S1, finite element modeling is conducted on the aircraft structural part subjected to electron beam fuse deposition forming, and the aircraft structural part is divided into a plurality of different areas; s2, for the aircraft structural part in each area, determining that the non-main stress direction is the electron beam fuse deposition forming height ST direction of the aircraft structural part in the area; and S3, in the ST direction, the aircraft structural part is formed by laying a plurality of deposition layers, in the deposition layers, the direction perpendicular to the L direction of the forming path is the T direction, the laying layers with the T direction consistent with the main stress direction of the aircraft structural part serve as first-class laying layers, the laying layers with the T direction forming a set angle with the main stress direction of the aircraft structural part serve as second-class laying layers, and the laying layers with the T direction forming a set angle with the main stress direction of the aircraft structural part serve as third-class laying layers. And the first-class laying layers and the second-class laying layers are arranged in a staggered mode to form the aircraft structural part. The structural weight is reduced, and part deformation can be effectively restrained.
本申请属于飞机部件设计技术领域,特别涉及一种电子束熔丝沉积成形结构的铺层设计方法。该方法包括:步骤S1、对进行电子束熔丝沉积成形的飞机结构件进行有限元建模,将飞机结构件划分为多个不同区域;步骤S2、对每个区域的飞机结构件,确定非主受力方向为该区域飞机结构件的电子束熔丝沉积成形的高向ST向;步骤S3、沿ST向,飞机结构件由多个沉积层铺层形成,在沉积层中,与成形路径L向垂直的方向为T向,将T向与飞机结构件的主受力方向一致的铺层作为第一类铺层,将T向与飞机结构件的主受力方向成设定角度的铺层作为第二类铺层,第一类铺层与第二类铺层交错布置形成飞机结构件。本申请减轻了结构重量,可有效抑制零件变形。
