波纹壳的摄动解法

The Perturbation Solution of Corrugated Shells

应用扁锥壳的非线性大挠度理论，研究了在均布载荷和中心集中载荷下，具有光滑中心的锯齿形和梯形波纹壳。采用摄动法和幂级数方法，得到了波纹壳的弹性特征。本文的解答符合实验结果。

The corrugated shells with a plane central region and toothed or trapezoidal corrugation under uniform or concentrated load are studied by utilizing the nonlinear theory of large deflection of shallow conical shells. The elastic characteristics of corrugated shells are obtained by using the perturbation and power series method. The theoretical results in this paper agree with previous experimental results.
