| 摘 要： | 采用大挠度弹性理论和中心差分法分析了拉压变形和弯曲变形之间存在弹性耦合的非线性薄梁结构对冲击波载荷作用的大挠度瞬态响应。为了充分描述冲击波载荷的强度大小，文中应用了冲击波载荷的冲量概念。通过进一步研究模态数、时间步长、拉－弯耦合、拉／弯刚度比、冲击波冲量对挠度响应的影响，得到了一些有用的结论。

| Abstract: | The large-deflection transient response of nonlinear thin beam structure with ten-sion-bending coupling to blast loading is analysed by the theory of large deflection elastic beamand central difference method in this paper.An impulse concept is adopted to fully describe the intensity of blast loading.Some very useful conclusions are obtained from further investigations ofthe influences of mode number, time step,tension-bending coupling,tensionl bending stiffness ra-tio and blast impulse on the deflection responses. |
