智能结构载荷识别的有限元反分析方法
FINITE ELEMENT INVERSE ANALYSIS OF LOAD IDENTIFICATION FOR INTELLIGENT STRUCTURES
-
摘要: 利用阻尼最小二乘法建立了一种识别作用于结构上的载荷的大小和位置等参数的反分析方法．该方法能够根据结构中部分点的位移测量值进行载荷识别，并与有限元法和有限差分法相结合以增强它的适用性．算例表明该方法的有效性．Abstract: Based on the least square method, a method is presented to identify the load on the structure by the displacements of some points in the structure. The finite element method and the finite-differrence method are introduced to apply the method in practical Engineering problems. An example shows that the method is effective.
