摘要
本文推导出轴向荷载作用下变截面圆形薄壁杆弹性稳定问题的基本微分方程,并用解析法求出问题的特征解。根据杆件不同的几何参数,将数值计算结果绘成图表,以供参考。
The fundemental differential equation for elastic stability of the circular thin walled column with variant cross section subjected to axial pressure is derived in this paper, and the characteristic solution is obtained by an analytic method. Numerical calculations are carried out for different geometric parameters of the column, and the results are presented by diagrams for reference only.
