传感器优化布设在桥梁健康监测中的应用

回顾了振动模态分析技术中关于传感器最优布点方法的研究，针对桥梁结构健康监测中有关指纹析识别以及模型修正所需的模态动态信息，提出了一套传感器优化布设的方案，目的在于迅速有效地从一个自由度繁杂的结构模型中选择出关键的测点位置，在含噪声的环境中实现对结构状态改变信息的最优采集，改善早期对大型柔性结构的整体探伤能力。

Application of Optimal Sensor Placement Algorithms for Health Monitoring of Bridges

Based on the previous work of the optimal sensor placement algorithms for modal experiment, a methodology is provided for optimally locating sensors for health monitoring of bridges. The program starts with a small intuition set of measure points. Then by making the mode shapes of interest as linearly independent as possible and making the measured kinetic energy optimization, a reasonable additional set is figured out and the initial set is checked. Finally, by using the sensitivity analysis and Fisher information matrix, a more suitable set of sensor location can be determined for the monitoring of the critical parts of the bridge.
