| In modern manufacturing, mechanical assembly in high volume production relies upon the removal of specially positioned components in a line from the vibrating spiral feeder bowl, which feeds the parts and reassembles hundreds of pieces. A bowl with a helical track vibrated by the electromagnetic leaf spring and gravity is employed to move or carry the parts on the non-linear dynamic vibrating spiral feeder bowl. The vibrating spiral feeder bowl depends on vibration correspondingly involving in chaotic regions and frequent repairs. Some of the inadequacies to the vibrating spiral feeder bowl are bowl top surface wear due to friction as a result of repeated impacts, the dynamic behavior for continuous vibration and material structural deformations that affects its accurate performances. To overcome these problems, a model of the located on the electromagnetic leaf spring system was investigated to resolve bowl material, geometric parameters and mechanical stresses under vibrating forces and friction. There is not enough literature available regarding physical parameters related to static stress modeling and von Mises criteria about vibrating bowl and leaf spring. Therefore, the research goal was to study structural static stresses, strain and von Mises failure mode caused by centrifugal stresses, strain and vibrations in ANSYS. The main distinction of this work from previous researches is the analytical analysis of the physical parameters associated to structural and mechanical behavior model of vibrating spiral feeder bowl according to ISO 10816 standards. The cast aliminium material integrated with spring leaf behaviour simulation for the vibrating spiral feeder bowl was analysed by finite element structural static, and von Mises analysis in ANSYS and the computational model was refined analytically. |
