摘要：

针对江山碗窑水库5#表孔弧形工作闸门空载启闭过程中存在异常振动问题，通过弧门支铰及埋件位置现状检测、不同开度下弧门位置检测、振动测试、工作应力测试、启闭力测试等原型试验以及弧门振动模态理论分析，对弧门异常振动的原因进行了深入的研究。研究结果表明：弧门上主梁左右2测点（原同一高程）的高程差随弧门开度的增加而增加，当弧门开启7.6 m时，高程差达88 mm，这和左侧支铰轴高层偏差均超标是引起弧门异常振动的2大因素；弧门异常振动主要发生在4.39 m开度内,为刚体模态中绕上轴线的旋转振动；该振动在左支臂上表现尤其显著。研究成果对表孔弧门异常振动运行的安全评估和故障处理具有重要参考价值。

Abstract:

The aim of this study is to solve the problem of abnormal vibration during non-load working of No.5 arc gate of the surface outlet of Wanyao Reservoir in Jiangshan City. The causes of abnormal vibration were analyzed firstly by detecting the current position of the gate hinge and embedded plates, the gate position at different openings, and then by prototype tests including vibration test, working stress test, lifting and closing force test, as well as theoretical modal analysis on arc gate vibration. Results showed that there were two main causes of the arc gate abnormal vibration: the first, when the gate opened to 7.6m, the elevation of the right point on the upper main beam was 88mm higher than that of the left point; the second, deviation of the elevation of left hinge axis exceeded the standard tolerance. Abnormal vibration was especially obvious on the left arm, and mainly happened when the gate was opened within 4.39m, which is a rigid rotational vibration around the upper axis. The research is a significant reference for the safety assessment and fault treatment of arch gate.
