A new technology for producing AZ31 magnesium alloy aircraft brackets with a triangular outline

Abstract

Purpose

This paper aims at working out an innovative technology of aircraft brackets with a rib of a triangular outline manufacturing from magnesium alloy AZ31 based on forging process.

Design/methodology/approach

Theoretical analysis of the assumed forming process of brackets with a rib of a triangular outline was made on the basis of computer simulations in software Deform 3D, basing on finite-element method. Research works were conducted for a magnesium plate from magnesium AZ31 alloy. Considering calculations, the scope of technological parameters guaranteeing the process proper course and good quality of the product was determined. Theoretical results were verified using a three-slide forging press.

Findings

The experiment’s results confirmed the effectiveness of the worked-out technology and the rightness of its application at manufacturing of brackets from non-ferrous metals used in the aircraft industry.

Practical Implications

The main aim of the worked-out method is manufacturing of aircraft brackets from light metals alloys, e.g. magnesium alloys. This technology can be applied for plastic forming of flat parts with ribs of a triangular outline. Manufacturing of aircraft brackets, basing on that worked out by the author’s technology, will allow for the improvement of products’ quality and reduction of their manufacturing costs.

Originality/value

The originality of this paper is based on the presentation of a new, innovative manufacturing technology of brackets with a rib of a triangular outline. The presented method is a unique one at a national (Poland) and global scale, and its assumptions underwent patent protection.
