摘要
以沿曲线等弧长取n个点的曲率半径组成的n维向量为特征向量来描述曲线 ,并利用神经网络实现了曲线类型的识别。与前人的工作相比 ,本文提出的方法能充分考虑曲线形状对零件冲压成形性的影响 。
Curve style recognition is one of the critical technologies in Intelligent CAD for automobile cover panel.Several methods have been developed to calculate the similarity between curves,which classify curves by the coordination of the points on the curves or the area covered by the curves.These methods have given little concentration on the relationship between the shape of the curves and the formability of the cover panel.A new method,which describes the curves with radius of curvature is presented and ANN is used to classify the curves in this paper.It is in the field of Intelligent CAD that the new method is more feasible than the former ones.
