Combined with finite element numerical simulation analysis, the hot-spin forming technology of cylindrical AZ80 magnesium alloy parts was studied in the paper. e multipass hot-spin forming of magnesium alloy shell parts was simulated by the ABAQUS software to analyze the stress and strain distribution and change during spinning for the preliminary test process parameters in the magnesium alloy spinning test. en, the process parameters were optimized during the hot spinning test, especially the matching relationship between temperature parameter and thinning rate parameter, and the hot spinning magnesium alloy shell parts with the expected technical specifications were finished. Simulation Analysis of Hot-Spin Forming ofCylindrical Magnesium Alloy Parts e strong spinning of the cylindrical part (generally called flow spinning) is a typical partial loading, point-by-point deformation forming process, which has the advantages of labor saving, material saving, and flexibility. It is a metal near

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 tantalum tungsten alloy has excellent mechanical properties which is used extensively in many fields, in this paper, the spinning manufacturing simulation model was built for the tantalum tungsten alloy cylinder part based on finite element method, the spinning process parameters were designed according to the actual working conditions, the stress, strain and the materials flowing behavior during the spinning process were analyzed, the spinning manufacturing results was obtained. Then the influence of spinning wheel working angle, spinning wheel fillet radius, spinning feed rate and thinning rate on equivalent strain was discussed.
