| 摘 要： | 介绍了两种输水廊道的正、反两种弧形阀门振动试验成果：在“平底式”廊道中，阀门在小开度很窄运行区间内产生了自激振动，而“底扩式”廊道则在大部份运行过程中产生了强迫振动。对模型设计的有关问题作了论述。

| Abstract: | The vibration test results obtained from two kinds of valves, i.e., reverse and positive tainter valves in two kinds of culverts, are briefly presented. In the flat bottom culvert, the self exciting vibration of the valve is generated as it is operated in small opening region; but, in the bottom enlarged culvert, the forced vibration occurs as it is worked at large part region. Moreover, some comments upon the related problems to model design are also made. |

| Keywords: | valve vibration self exciting vibration forced vibration hydroelasticity |
