摘要

采用水力学边界条件优化和结构优化是降低水工弧形闸门流激振动的重要措施,但这些措施对流激振动的削弱仍然有限,且不能应用于已建成闸门的减振。采用结构控制的方法是解决流激振动问题的进一步措施。针对某大型水利枢纽导流底孔弧形闸门,在闸门上布置若干MR阻尼器,采用优化模糊半主动控制来减小振动。计算结果,表明采用优化模糊半主动控制能有效地抑制弧形闸门流激振动反应,可取得与LQ半主动控制相当的效果。
Improving hydraulic boundary condition and optimizing structure of tainter gate are very important measures to suppress the flow-induced vibration of hydraulic tainter gate,but these measures,which can be only taken before construction,are not enough for reduction of the vibration.Employing structural control method is a further way to solve the problem.This measure is significant for vibration mitigation of already existing tainter gate.Optimized fuzzy semiactive control strategy was proposed to reduce the vibration of certain tainter gate installed with magnetorheological(MR) dampers in certain key large hydraulic project.The simulated result shows that MR dampers can diminish flow-induced vibration of the arch sluice effectively under this strategy and the effectiveness is equivalent to that of linear quadratic(LQ) semi-active control strategy.
