| 摘 要： | 从自由振动微分方程出发详细推导了残余力向量的表达式，以一矩形等截面悬臂粱为研究对象，利用残余力向量法，通过数值模拟，实现了对预制裂纹粱的损伤识别；鉴于实际结构建模的误差，提出了改进的残余力向量法，并在振动实验中验证了该方法更适合实际工程应用。

| Abstract: | The representation of residual force vector was derived in detail on the basis of free vibration differential equation. A cantilever beam of rectangular cross section was studied by numerical simulation and experiment. The above mentioned method was applied to the experiment and its efficiency was demonstrated through several damage simulations. As the present residual force method depend on the accuracy of the structural analytical model that one used, It is improved to make it suitable for damage detection on practical engineering. |
