在模态应变能法的基础上提出了一种改进的桥梁传感器布局算法,并利用ANSYS建立有限元模型,施加相应约束对模型进行模态分析,然后根据改进的模态应变能法提取相应的结果,继而用模态置信度准则(MAC)对其进行评价,最后通过武汉理工一桥工程实例得出经过优化的传感器布置方案性能指标要优于传统的传感器布置方案,为结构检测传感器的布置方式提供了另一种可供参考的方式。 Based on the modal strain energy method, an improved bridge sensor layout algorithm is proposed, and the finite element model is established by ANSYS. The model is modeled by applying corresponding constraints. Then the corresponding modal strain energy method is used to extract the corresponding Results, and then use the modal confidence criteria (MAC) to evaluate them, and finally through the Wuhan Polytechnic Bridge project examples obtained optimized sensor placement scheme performance index is superior to the traditional sensor arrangement scheme for the structure detection sensor arrangement Way provides another way for reference.
