摘　　要：通过在迎水面典型特征点设置拾振器,对滚筒闸门的简化模型(横置于清水水流中的钢质圆筒)在不同工况下的动力特征和流激振动响应的观测。评定滚筒闸门的安全性,确定运行不利开度,并对闸门的安全运行提出建议。Through setting vibration pickup device on typical characteristics points of the upstream face, dynamic characteristics and flow - induced vibration response of the cylinder gates＇simplified model （ steel cylinder in water） under different working condition are observed. Moreover in this paper, Security of the cylinder gates is evaluated. Unfavorable opening degrees are determined and the methods of the gates safe operations are proposed.
