中文摘要：

引入面导纳的概念对结构的分布载荷进行识别。推导得到有限板的平均面导纳公式，并给出平均面导纳的数值计算方法。最后，结合复功率法给出了由子系统分布载荷的输入功率识别分布载荷的方法，通过数值仿真验证分布载荷识别方法的有效性和可行性。

英文摘要：

The concept of surface mobility is introduced to study the identification of distributed loads based on SEA in the paper. The expressions of average surface mobility for the finite plate are derived. By discretizing the acting area, a numerical computation method for average surface mobility is developed. Finally, combining with the complex power method, an identification approach of load power spectrum of distributed loads from the input power of subsystem is set up. The proposed method is validated numerically through an example.
