Metal mounting seat novel structure weight reduction design method used for cartridge receiver

Abstract

The invention discloses a metal mounting seat novel structure weight reduction design method used for a cartridge receiver. The method comprises a mounting hole center circle diameter, a rivet hole center circle diameter, a mounting seat weight reduction external diameter, a mounting seat external contour diameter, a mounting hole external diameter, three inverted circular beads, an internal contour diameter, two weight reduction hole diameters, a mounting threaded hole height, a mounting seat height, a mounting seat riveting thickness, a chamfer, two inverted circular beads, an internal threaded hole diameter, a rivet hole diameter and two positioning angles. The mounting hole center circle diameter, the rivet hole center circle diameter, the mounting seat weight reduction external diameter, the inverted circular beads and the weight reduction hole diameters are subjected to weight reduction layout design. The metal mounting seat novel structure weight reduction design method has the advantages that a three-dimensional structure parametric modeling method controlled by an expression and a law curve can be applied to quickly revise different mounting seat layouts, the quick design of a remodeled product can be carried out, and the method is suitable for designing a composite material cartridge receiver metal mounting seat.

Description

technical field [0001] The invention relates to the field of structural design, in particular to a novel structural weight-reducing design method for a metal mounting seat used for a casing. Background technique [0002] The composite case for aero-engines has been designed with the structure of composite shell, front and rear metal mounting edges, and metal mounting seat. Since aero-engines need to meet the weight index requirements and pursue lighter weight, the number of metal mounts on the outer culvert casing of composite materials is relatively large. At present, the metal parts used for outer culvert casings of composite materials are mostly expanded by columns. Hole weight reduction design method, the design of structure weight reduction optimization according to the installation hole position is still blank. Contents of the invention [0003] The purpose of the present invention is to design a layout for weight reduction compared with traditional weight reduction...
