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．
Using the method of damping least squares, an inverse analysis method is developed to identify the parameters such as the size and position of the load acting on the structure. The method can identify the load based on displacement measurement of some points in the structure and combine it with finite element method and finite difference method to enhance its applicability. The example shows the effectiveness of the method.
