深水叠梁闸门自振特性研究
Study on Vibration Characteristics of Deep Stoplog Gate
摘要
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 gate frequency gradually drops and eventually tends to a horizontal line with different length selection of water body in fluid-structure interaction calculation model; and (c) the first-order vibration mode changes with the increase of water body range and the local vibration in the direction of flow changes to the overall vibration along the flow direction.关键词
