中文摘要：

为了研究曲边柱壳受动态内压载荷作用下的变形规律，建立了精确考虑壳体几何构型的非线性动态控制方程，提出了一种基于静力变形模式的动态响应计算方法，然后通过能量方程建立了均匀内压作用下曲边柱壳动态解的增量求解算法，求解结果与有限元方法LS-DYNA计算结果十分一致。分析了加载速率和载荷形式对曲边柱壳动态响应的影响，发现加载速率和载荷形式可以较大程度地改变曲边柱壳的动力学行为，因此可以通过改变动态加载速率和载荷形式来控制曲边柱壳不同的动态特性。

英文摘要：

To study the nonlinear dynamic deformation law of curved boundary cylindrical shell,the governing equations for the dynamic deformation of the shell were established in which the geometry configuration was accurately considered.A new method for obtaining the dynamic solution for the shell with uniform load was proposed based on the static deformation modes from our previous work, and the incremental numerical algorithm was presented through energy equation.The obtained solu-tions were verified by comparing with the results from LS-DYNA.Finally,the influences of load pa-rameters to dynamic deformation of the shell were studied,and it is found that the dynamic responses can be greatly changed by the loading rates and load forms,and different dynamic characteristics of the curved boundary cylindrical shell can be realized by changing load parameters.
