Simulate Measure for Spring Back of Autobody Panel's Edge
With the higher quality requirement of automotive assembly, the demand for forming precision of the stamping part gets higher. The simulation of resilience around the edge of drawn parts of autobody panels has become a hot spot of automotive field. Currently, the study on resilience mainly focused on the principle of resilience of bent parts and its relative control whereas the investigation on resilience of drawing process is quite less. This paper has studied the object of automobile cover panel through comparison of captured contour to calculate the resilience of edges of part, resolve the resilience problems of drawn part, for which the traditional calculation method and CAE software, focusing on bending resilience issues, couldn’t provide their solution.
