摘要
从动水压力、动力特性和振动响应观测3个方面出发,对弧形闸门流激振动原型观测中采用的研究方法、测试技术、分析方法及存在的难点问题进行了探讨.通过采用现有的几种闸门振动安全评价方法,分别对几种典型的弧形闸门进行了评价,并对评价结果进行比较.分析结果表明:大部分闸门的评价结果较为一致,但少数闸门的评价结果出现了偏差,闸门的振动安全性评价有待形成统一的评价标准.
Research method,testing techniques,analytical methods and existent problems used in Radial gate flow-induced vibration prototype observation were discussed from dynamic water pressure,vibration characteristics and dynamic response observation.By using the current major safety evaluation method which exists at domestic and international areas,several domestic typical radial gates are analyzed.The evaluation resultsare more consistent for most of the gates,but deviation evaluations are suitable for a small number of gates,the security evaluation of the gate vibration needs to form unified evaluation criteria.
