| 摘 要： | 介绍桥梁结构模态测试中传感器优化布置的序列法,该法以模态置信度MAC矩阵的最大非对角元为目标函数,采用逐步累积或逐步消去的方法对传感器进行优化布置,直到传感器数目最理想、位置最优。最后举例说明了该法在桥梁结构模态测试中的应用。

| Abstract: | This paper introduces the serial method for optimal placement of sensors in the modal tests of bridge structure.Using the maximum off-diagonal element of Modal Assurance Criterion matrix as the target function,the method can optimize the placement of the sensors by means of gradual cumulative or gradual reduction until the numbers of the sensors become most ideal and the locations of the sensors become optimal.In the end,the paper gives examples to show the application of the method in the modal tests of the bridge structure. |
