3-D finite-element simulation of the cold forging of helical gears

摘要: Abstract This article illustrates the use of finite-element method to simulate forging 3-dimensional complex industrial parts. The FORGE3 code, which can cold and hot parts is presented together with a thermo-mechanical formulation its numerical resolution. It known that in an updated lagrangian approach using convective mesh, degeneration mesh occurs very rapidly. An automatic generation procedure for 3-D geometries has been developed enables creation initial billet as well remeshing. technique allows simulation whole process quandratic tetrahedral elements. In order show effectiveness method, lateral extrusion helical gear computed. results computation be carried out described remeshing it applied successfully even more geometries.
