The Simulation Of The Manufacture Feature-based For Sheet Metal Parts

With the widely development of the research for stamp-forming finite element simulation,more people began to solve the arduous problem which using finite element method to know the stamping of large scale complicated ramming components (For example various spare parts for automobile),and making perfect continuously。The automobile body panel components molding relates directly to the components quality。This topic unifies Ningbo Moaning company automobile development, takes shape in the process to column outside plank, conducts the experimental study, and has outlined the panel ramming molding production mechanism in this foundation, the finite element value simulation technology correlation elementary theory, has analyzed the influence molding value primary factor. Then developed has taken shape the process simulation to the components, through to the analogue result analysis, after adopted the corresponding improvement and the revision measure molding on the simulation analysis, obtained the effect good craft model. After uses this craft model to carry on the ramming components which the mold processing produces to carry on the survey, and to surveyed the data and the simulation analogue result carries on the contrast analysis, for reasonably compensated the molding to provide the effective way, and for overcame in the mold performance history the molding question to plan to provide the guide and the reference.This article labor opposes the new vehicle type pressing part which later will develop to improve the product quality to have the vital significance.
