摘要
本文在分析水工弧形闸门结构的构造特征及实验模态分析的基础上,用灵敏度分析方法进行动态特性优化计算,通过工程实例的计算,给出了弧形闸门动特性的优化结果.指出,增加弧形闸门整体构造刚度是提高闸门自振频率的途径.
On the basis of structural-feature analysis of tainter gates used in hydrualic structures and experimental modal analysis, a method of sensitivity analysis is used for dynamic characteristic optimization. The computation of a practical engineering problem gives the optimization results of the dynamic characteristics of a tainter gate. The results show that the natural frequency can be increased by the increase of structural rigidity of the tainter gate.
