Study on Deformation Computation of Sluice Gate By Using Finite Element

平板闸门是一种典型的空间薄壁结构体系,由一系列板、壳、梁、杆等构件组合而成。有限元计算模型的选择考虑到各构件的几何性质、变形特征和受力方式以及相互作用关系等,以正确反映出闸门的整体作用以及各构件的实际工作状态。本文分析有限元方法计算闸门变形基本原理,并以实例进行计算,得到较为合理的计算结构,验证有限元计算闸门变形的可行性。

The plate gate which is constituted of boards,shells,beams,poles and so on is a typical spatial thin-wall structural system.The computational model of finite element could exactly reflect the entire fuctions of sluice gates and the working condition of every component through considering the geometric properties,the deformation features,the forced form of every component and the interaction relationship among them.Here,through analyzing the basic principles for calculating the deformation of gate with finite element method by examples,the more reasonable calculation structure could be obtained,and the feasibility for calculating the deformation of gate by using finite element could be verified.
