本文根據冬季有運行要求的閘門及低水頭弧形閘門需要採取防凍措施的實際情況，研究設計了一種電熱型防凍裝置。In this paper, ansys, the software on finite element analysis, is made use of processing the static and modal analysis on the preliminary models and its " modified ones. by analyzing the results, we can conclude that the stresses on the components of the modified models are tended to equilibration and the location of the branches " brace can also influence stresses and translations on the branches. in addition, the values of the intrinsic frequencies on modified models " are larger than the ones on preliminary models, but the ranges of the frequencies on both models are almost same
傳統的弧形閘門的支臂結構基本上都是三角架式的，這主要是因為按平面體系進行計算的傳統設計方法忽略了結構的整體性及弧形閘門的空間結構特點，設計得比較保守，而實際上，將其改為a型結構也存在可行性，本文是利用有限元分析軟體? ? ansys對原模型及修改模型分別進行靜態和固有頻率的計算，通過分析比較其結果可知，支臂改為a型后會使閘門的整體受力趨于均勻，即原模型受力大的部件其應力變小，而原模型受力小的部件其應力會變大；而且a型支臂的支桿在不同的放置位置對支臂的應力和位移變化也有一定的影響。Radial gate is one of type of gate used widely in hydraulic structure engineering
弧形閘門是水工結構工程中使用最廣泛的閘門型式之一。Unsteady separated flow, produced during the gate - opening period in the reverse radial gate tunnel of a high - lift shiplock, is characterized by negative pressure and high velocity as well as their intense fluctuations in space and time and could easily result in various harmful phenomena such as cavitation, gate vibration and sonic boom, which have been observed and confirmed by prototype and physical model tests
高水頭船閘輸水反弧閥門開啟過程中，后廊道內發生急變分離流，負壓、高速水流以及壓力與流速的劇烈時空脈動變化容易誘發空化空蝕、門振和聲震等有害現象已被原型觀測和物理模型試驗研究證實。In order to solve those problems, this article adopts the energy method to analyze the stability of the major frame of steel arch gate to make up the weakness in the current standards and found the calculating models of the stability of the whole major frame of the steel arch gate. it also presents the general formula for calculating the eigenvalue and the precise equation of the calculating the length coefficient of the steel arch gate frame by using the energy method and choosing the proper experiment function
本文主要採用能量法對弧形鋼閘門主框架線彈性穩定性進行分析與研究，建立單柱概化弧形鋼閘門主框架整體穩定的計算模型，並通過選擇合適試解函數，應用能量法給出特徵值方程及弧門框架穩定性計算長度系數精確解的公式，提出一個基於該模型方便工程設計的實用計算公式。分享友人
