水电站门式起重机门架结构有限元分析方法

Finite element analysis method for gantry structure of gantry crane used at hydropower station

本文通过对几台典型的水电站门式起重机门架结构建立有限元模型的研究并进行有限元法计算,结合电测结果进行对比分析,总结了设计计算这类结构的有限元分析方法。

A study is carried out for creating finite element models ot gantry structures of several typical gantrycranes used at hydropower stations. Calculation is made using finite element method. After a comparativeanalysis with the result of electronic measurement, a finite element analysis method is summarised forcalculation of such structures.
