Abstract

The invention relates to a method for generating a powder-coated sintered support structure of an aircraft structural part based on a space lattice. This method first calculates the bounding box of the support structure; secondly, calculates the node positions in the support structure within the bounding box; then judges the necessity of generating support rods according to the part features and node positions; finally, according to the support rods and the user input Sketch generates solids and designs fillets or chamfers in support structures. This method has the characteristics of high efficiency and wide application range. It can be used for the rapid generation of support structures for parts with arbitrary shapes for the additive manufacturing method of powder coating and sintering, and 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 ...
