Abstract: The stress and strain of a miter gate of ship lock are analysed using the method of Ansys. In the case of a miter gate, the results of the method of Hydraulic and Hydroelectric Engineering Specification for Design of Steel Gate DL/T5013-95 (Here after called Specification) and Ansys are compared. It has shown that there are some differences between the results from the method of Ansys and from the method of Specification. The reason is analysed,and the disadvantages of the method of Specification are explained, then the miter gate’s dynamic characteristic is analysed as well.

摘要： 应用Ansys对船闸人字门的应力、应变进行了分析计算。以某人字门为例,把《水利水电工程钢闸门设计规范DL/T5013-95》(以下简称《规范》)算法的结果与有Ansys的计算结果相比较。计算结果表明,Ansys的计算结果与《规范》算法的结果有一定的差异,分析产生这种情况的原因,说明了《规范》算法的一些缺陷,并分析了该人字门的动态特性。
