摘要
利用有限数目的传感器测量响应来重构未测点的多种响应。该方法是基于卡尔曼滤波算法,考虑传感器位置的优化,并融合应变、位移和加速度响应信息,实现从已有的有限数目测量响应数据到结构上未测点响应的预测。用桁架结构数值模拟了该方法的使用,并验证了该方法的有效性和适用性。
This paper aimed to present a new method of multi-type structural response reconstruction at the locations,where sensors was not available by using limited number of sensors. The multi-type structural responses refer to strain,displacement and acceleration responses. Considering the optimal locations of sensors,the responses at unmeasured locations were reconstructed based on Kalman filtering algorithm. A two-dimensional truss structure was then presented as a numerical example to investigate the effectiveness and accuracy of the proposed approach. The results indicated that the reconstructed responses were in good agreement with the real ones.
