Static And Dynamic Finite Element Analysis Of Double Cantilever Steel Beam Gate

The stress analysis of steel gate is always the focus of water conservancy workers.Due to the limitation of loading and monitoring problems,the research on the stress analysis of steel gate is mostly dependent on the numerical method.The gate of Dongwushi reservoir double cantilever steel stoplog operation mode and the stress characteristic,finite element numerical simulation analysis of static and dynamic modal of the steel gate,on the basis of static analysis to calculate the main beam,the panel should be the maximum shear force and the maximum bending stress of web,and the steel gate the dynamic modal analysis,analysis under different conditions of natural frequency and corresponding vibration frequency of the vibration,theanalysis results show that the safety analysis of gate static and dynamic two methods to verify the gate the most dangerous position,also shows that the model is reliable.The Dongwushi reservoir mainly in flood control,water supply for the first,but also relates to Large Water Conservancy Hydroelectric Power and environment,farming and other comprehensive planning,but because the relief built in Hongdong for a long time,the main structure of reservoir engineering problems,threaten their safety engineering.In order to ensure the important cities and infrastructure and safety in the downstream of the reservoir,it is necessary to strengthen the reservoir.Dongwushi reservoir pressure arch culvert type nipple without pressure,3 holes,and both ends of the cantilever structure in practical engineering the basic application examples,there are substantive issues to study and solve many.Through the analysis and study of the construction project of the flood relief project in Hongdong,the temporary closure of the upper gate is carried out under the water,and the two cantilever gates are used to block the gate.In view of the relief of Hongdong deep water plugging gate as shown in Figure 1,the establishment of double cantilever steel stoplog finite element analysis model of statics and dynamics of gate vibration,the stiffness of the gate to start using ANSYS software.In view of this,this paper based on the finite element method for stress analysis of steel gate Dongwushi reservoir,explore the effect of the load of steel gate stress forms from the macroscopic angle,so as to provide reference for practical engineering.
