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 fluid-structure coupled wet-wet modal synthesis method proposed by the author, this paper calculates the first 8 modes of the power plant gate, and shows the superiority of this method in the dynamic calculation of complex structures. In particular, when a sub-structure information is wrong, it is not necessary to recalculate it. The sub-structure needs only to be corrected and then read, which obviously improves the calculation efficiency. And the calculation of working conditions were tested accordingly. We can see from the comparison that the two are more consistent.
