摘要
本文根据作者提出的流固耦合拟湿模态综合法原理计算了电站闸门的前8阶模态,显示了该法在复杂结构动态计算中的优越性。尤其当某一子结构信息出错时,不必重新计算,只需对该子结构进行改正后再读算,明显地提高了计算效率。并对计算工况进行了相应试验。从比较可知,两者较一致。
Based on the pseude-wet modal synthesis for fluid-structure coupling vibration method the calculations from the 1st mode to 8th of a power station's sluice gate have been performed. The results show the superiority of the method in the dynamic calculation of very large Complex structures. Especially, when the messages of some substructure are out of order, only the revisions of some substructure are necessary to be performed and the calculation can be carried out continuesly without resolving the eigen equations Therefore the efficiency of calculation is raised obviously. A comparison of numerical results indicates that the method used in this paper is in relatively close agreement with the experiments.
