Analysis of stamping process for engine cover hood-inner of automobile

The strain distribution of engine cover hood-inner of auto during stamping process has been analyzed with CGA (circle grid analysis)technology.The deformation style and possible risk zone of part in high strain zone have been studied.The decreasing of the wall thickness for stamping part has been analyzed.The influence of material properties to the part forming process has been discussed.Finally,as per the stamping results,the suggestion of die-adjusting has been given.
