摘要
本文给出了计及剪切变形和转动惯性效应的正交异性圆柱壳受冲击扭矩作用的轴对称运动方程的无量纲形式；应用广义特征线理论得到了沿特征线上的相容方程，并采用数值积分方法分析了有限长圆柱壳的波传问题。该方法适于更为复杂的模型。
In this paper, the non dimensional axisymmetrical motion equations of orthotropic circular cylindrical shell under impact torque by considering the shear deformation and the rotational inertia effect are given. By using the generalized characteristics method, the compatibility equations on the characteristics are obtained. And the wave propagation of the finite length cylindrical shell is analyzed. The method can be used to analyze the more complicate models.
