圆柱壳体在移动集中荷载作用下的稳定性

Stability of Cylindrical Shells Subjected to Moving Focused Loads

考虑了横向剪切力和切向位移的影响，给出任意长圆柱壳在动荷载下的非线性稳定性方程，采用小扰动法级数展开，通过Ｌａｐｌａｃｅ变换求解，利用边界条件得出移动环荷载下的临界荷载。

The influence of transverse shear force and tangential displacement considered, the nonlinear stability equations of cylindrical shells of any length subjected to moving loads is deduced. The analysis is carried out with a series of expansion for small perturbed variables and double Laplace transform technique. The critical loads of the moving-ring load are obtained using the boundary condition.
