摘　　要：水利水电工程中双向门式启闭机各机构运行工况复杂,设计过程中需要考虑不同荷载组合下门机结构的的静、动力学及抗倾覆稳定特性。针对某水电工程坝顶双向门机,利用顺序荷载传递方法对小车架和门架结构进行了空间有限元分析,为设计提供了详细可靠的计算结果。The operating conditions of mechanisms of the two-way gantry hoist in of water resources and hydropower projects are complicated.During their design,characteristics of static dynamic mechanics and stability against turnover of the gantry hoist at different load cases shall be considered. Based on the design of the two-way gantry hoist at dam crest of one hydropower project,the trolley rack and the gantry structure are analyzed in term of finite element by application of sequence load transit method. This provides its design with detailed and reliable calculating results.
