摘　　要：传感器的优化布置作为水工钢闸门结构健康监测的首要环节,对于其监测的准确性与合理性具有重要意义。针对水工钢闸门在结构健康监测中加速度传感器优化布置的问题,以弧形闸门为例,建立流固耦合有限元数值模型,提出了一种结合有效独立法—加权模态置信准则—曲线拟合(EI-WMAC-CF)的传感器优化布置方法,对比分析了弧形闸门干、湿模态下的传感器优化布置方案。结果表明,所提方法能够适用于水工钢闸门结构健康监测中,能较好地解决水工钢闸门传感器优化布置的问题,且考虑闸门流固耦合作用下的钢闸门传感器优化布置方案更具有代表性。As the primary link of structural health monitoring of hydraulic steel gate, the optimal layout of sensors is of great significance to the accuracy and rationality of its monitoring. For the hydraulic steel gate in the problem of optimal placement of acceleration sensors in structural health monitoring and radial gate, the fluid-structure coupling finite element numerical model was established. This paper proposed a combined with effective independence method, weighted modal confidence criterion, curve fitting(EI-WMAC-CF) method of optimal placement of the sensor, and did comparative analysis of optimal sensor placement of radial gate under dry and wet modal. The results show that the proposed method can be applied to the structural health monitoring of hydraulic steel gate, and can better solve the problem of the optimal sensor layout of hydraulic steel gate, and the optimal sensor layout of steel gate is more representative considering the fluid-structure coupling of the gate.
