Cylinder and enlarged blades are used as test models for simulating the leading edge and concave surface of the blade.
用圆柱和放大的叶片做模型,模拟叶片前缘和叶盆凹面的流动。

The structure plate is composed of high-elastic structure, which is provided with an edge raised line, a middle raised line, a bottom flat surface and a bottom concave surface.
由高弹性结构构成,高弹性结构上设置有边凸条、中凸 条、底平面、底凹面;

Then experiments on springback in concave and convex edge flanging are carried out, significance of factors and their interactions are studied with statistics approach.
