| 摘 要： | 在考虑大变形、忽略阻尼的影响下,基于有限元软件ANSYS分析了加筋板在流固冲击载荷下的非线性瞬态响应.不仅将不同的冲击载荷形式,譬如阶跃载荷和三角形载荷,与流固冲击载荷对加筋板动力特性的影响进行了比较,还分别讨论了载荷峰值、冲击载荷持续时间、板厚、加强筋材料体积比和截面宽高比的影响,并对它们作了敏感度分析.

| Abstract: | Considering large deformation and neglecting damping effect,the nonlinear transient response of stiffened plates under fluid solid impact loading is analyzed in this paper based on the FEM software ANSYS.To examine the influence of different loading functions on the dynamic behavior of stiffened plates,in addition to the fluid-solid impact,the rectangular and triangular pulses are investigated.The influences of load amplitude,load duration,plate thickness,the ratio of stiffeners' volume to plate's and the stiffener's width to height ratio are discussed respectively,and the sensitivities of them are calculated. |

| Keywords: | large deformation stiffened plate fluid solid impact loading nonlinear transient response sensitivities |
