| 摘 要： | 根据深水中叠梁闸门的工作特点,建立闸门和水体的流固耦合模型,由不同的计算分析方法得出闸门的自振频率和特性,结果表明:流固耦合方法不仅能够说明流体惯性力对闸门的作用,同时还能体现出闸门与水体的相互作用,闸门与水体之间存在惯性耦合作用;流固耦合计算模型选取不同长度水体时,频率曲线逐渐降低并最终趋于水平;闸门第一阶振型存在一定的变化,随着选取水体范围的增大,顺水流方向的局部振动改变为整体顺流向振动。 |
| 关 键 词： | 叠梁闸门 流固耦合 自振特性 惯性耦合 |

| Abstract: | A fluid-structure coupling model of stoplog gate and water body is built according to the characteristics of the gate in deep water,and the natural vibration frequency and characteristics of the gate are gained through different calculation methods.The results show that:(a)the fluid-structure coupling method can not only explain the force of fluid inertia on gate,but also the interactions between the gate and water body,so there is inertia coupling between the gate and the water;(b)the distribution curve of... |
