摘要
提出了一种识别板结构受到的集中载荷的分析方法。采用正则化方法和最小二乘法,根据结构受载后的位移测量值反演所受的集中栽荷的大小和位置.获得了稳定收敛的解。另外,为了使解具有合理性,事先对要识别的量加以限制;最后给出了算例,识别的结果令人满意。
In this paper, an analysis method of the load identification for plate structures has been presented. Based on the displacement of the loaded structure and by means of the regularization method and the least square method, the size and the location of the load on the structure are back-calculated iteratively. In order to ensure the rationality of the solution, the identified parameters are constrained beforehand. A numerical example shows that the results are quite satisfactory.
