Abstract

The invention relates to a method for generating a powder laying and sintering supporting structure of an aircraft structural part based on a space lattice. The method comprises the steps of firstly calculating a bounding box of the supporting structure; secondly calculating the node position in the supporting structure within the range of the bounding box; then judging the necessity of generating a supporting rod according to the characteristics of the part and the node position; finally generating an entity according to the supporting rod and a sketch input by a user, and designing a rounded corner or a fillet in the supporting structure. The method has the advantages of being high in efficiency and wide in using range, aiming at a material adding manufacturing mode of powder laying and sintering, the method can be used for fast generation of the supporting structure of a part in any shape, and the method has a good application prospect.

Description

technical field [0001] The invention relates to a method for generating a supporting structure in the powder coating and sintering manufacture of aircraft structural parts. The method can quickly generate a CAD model of a support structure, thereby providing a rapid design tool for the support structure for powder coating and sintering manufacturing of metal structures, and belongs to the technical field of additive manufacturing of metal structures. Background technique [0002] At present, the additive manufacturing method of powder coating and sintering of metal structural parts has been widely promoted and applied. In the field of aviation manufacturing, this technology has been used in the development of special-shaped parts and complex pipe fittings. In the sintering process of metal structural parts, it is necessary to design a suitable support structure according to the process characteristics of the part, and sinter the support structure at the same time during the ...
