Power Spinning Study of Thin-Walled 5A06 Aluminum Alloy Cylinder with Longitudinal and Hoop Inner Ribs for Manufacturing Engineering

Abstract

In this paper, a three-dimensional finite element model of power spinning 5A06 aluminum alloy cylinder with longitudinal and hoop ribs is established. It reveals the laws of the stress and strain distribution of the longitudinal and hoop ribs in the spinning process, provides a theoretical guidance for the further optimization of process parameters for manufacturing engineering. The 5A06 aluminum alloy cylinder validated testes are through three stages. The first is to study spinning forming of the ten longitudinal ribs. The second is to study spinning forming ten longitudinal ribs and a hoop combined rib. The third is to study spinning forming qualified samples with ten longitudinal ribs and four hoop combined ribs. Optimization aspect of the aluminum alloy reinforced spinning parameters are obtained through simulation analysis and experimental verification, to provide an ideal theoretical guidance for further material application and production.

The Correlation between Texture Evolution and Recrystallization Behavior during Rheologic Forming of 2195 Al–Li Alloy Cylindric Shell

“…The spinning extrusion forming (SEF) process is a newly developed rheologic forming approach for manufacturing ribbed cylindric shells which involves the spinning of a ringshaped metal billet in various passes to extrude the rib structures [4]. The SEF process features a near-net-shape rheologic forming process, which addresses the problem of structural discontinuity during machining and internal stress concentration caused by welding [5]. However, the strong anisotropy of spin-extruded Al-Li alloy cylindric shells severely limits their further application as aerospace components [6][7][8].There are many factors affecting the anisotropy, of which the crystal texture is the most significant one [9,10] because the precipitated phase is precipitated along a specific orientation.…”

Research on Flange State during Spinning of AZ31 Magnesium Alloy Rotators

“…Magnesium alloy with high strength and low weight has increasingly become an ideal material for many important industries such as automotive, aerospace and weapon [1]. Spinning as an advanced manufacturing technology can effectively improve the utilization of materials; also improve the mechanical properties of materials [2]. The related researches are very limited about spinning of magnesium alloy rotators.…”
