정적-내연적 이론을 이용한 Cowl Top Otr 판넬 해석에 관한 연구
정동원,안현길,고형훈,문원섭 제주대학교 공과대학 첨단기술연구소 2005 尖端技術硏究所論文集 Vol.16 No.1
The static implicit finite element method has been effectively applied to analyze total cowl top otr panel stamping processes, which include the forming stage. Complicated and abnormal large size cowl top otr panel was analyzed by using commercial program called AutoForm. Analysis results examining possibility and validity of the AutoForm software and the factor study are presented. Furthermore, the simulated results for the total cowl top otr panel stamping processes are shown and discussed. Its application is being increased especially in the automotive industry for the cost reduction, weight saving, and improvement of strength.

A method is described for mapping a three-dimensional computer modelled surface into the two-dimensional plane. The technique is referred to as geometric modelling and provides in the computer a transformation between the flat sheet and the final surface. The initial blank shape represents an approximate development of the final formed three dimensional surface. It was used the initial constant area mapping hypothesis in this paper. This technique is intended to be developed as the basis of an interactive computer design capable of dealing with typical stamping process, including deep parts and complex shapes.
