摘要
作者用半解析有限条法分析了加筋圆柱壳。将壳体沿轴向划分为大单元、环向的力学量和几何量均展为正交系的级数形式,轴向采用多项式位移函数,与一般有限元法比较,该方法能以少得多的单元获得较精确的结果。
This paper analyses a cylindrical stiffened shell by the semi-analytic finite strip method. The cylindrical shell is separated into a number of large ring elements along the axial direction. The mechanical and geometric parameters are developed into orthogonal series in the circumferential direction, the polynomial interpolating function is chosen in the axial direction. Compared with general finite element method, this method can get higher precision with much tess elements.
