水电站隧洞式进水口事故工作闸门结构振动研究
|
摘要
悬吊于闸门井内的事故工作门受不平衡水推力而产生振动,闸门振动直接影响到门体结构安全和启闭设备正常运行。掌握闸门振动情况和研究闸门振动对门体结构的影响具有现实意义,文章就某隧洞式进水口事故工作门的振动进行了试验研究,得出闸门系统振动的特点,也提出了改进措施。
The unbalanced water pressure will cause the vibration of emergency and service gate when suspended in gate shaft,and the structure security of gate and the normal operation of hoisting equipment will be affected.The gate vibration and the influences on gate structure should be studied.The vibration of emergency and service gate for a tunnel-type intake is tested,and the improvements are proposed.
