| Abstract: |
| According to the state for valve vibration of navigation locks in the world and the achievement for design and study in navigation locks with high-lift in China after the 80's,this paper deals with the advance of culvert value vibration for navigtion locks. The character,value and affecting factors of the dynamic load at valve are analyzed. The importance of studying the dynamic characteristic of valve structure is expounded. A new technique for the structural dynamic characteristics and their optimization are filled in the gaps in this field, the valve vibration study become even more all-sidedness. The achieved notable results are discussed using the new technique to deal with the practical projects. These results supply for reference to design and study the high-lift lock culvert valve in the future. |
