摘要
在截锥旋转壳的力学计算中利用了环状样条单元,这种单元的构造采用沿截锥型旋转壳的经线方向和纬线方向分别取Hermite插值和样条函数插值,文中推导出了环状样条单元的单元列式。
For strenth analysis of cut cone shell,model of ringed spline finite super element is given.The interpolation of hermite function and B spline function come into use for given the element.The equations of stiffness matrix and load vector of spline finite super element are also set up.The analyzed result correspond well to the exist values.
