摘要
在分析各种解析解的优缺点的基础上,根据广义超比微分方程,推导出质量较大时各种端部组合柱的弹性屈曲解析解。然后评估近似计算公式的准确性和数值解。
Many scholars deduced the various analytical solution of the column buckling. Based on the analysis of the advantages and disadvantages of various analytical solutions, first according to the Generalized hypergeometric differential equation, to deduced quality larger at the end of the composite column of the elastic buckling analytical solution. Then evaluate the accuracy of the approximate calculation formula and numerical solutions.
