一种识别结构系统边界条件的新方法

A New Method for Identifying the Boundary Condition of Structural System

提出了利用特征值的灵敏度分析和振动模态参数相结合识别结构系统边界条件的新方法．文中详细地进行了方法的理论推导和算例分析，表明该方法有效，实际可行．

A new method,which uses the eigenvalue sensitivity analysis and vibration modal parameter for identifying the boundary condition of structural system,is presented.The theoretical derivation and examples calcuation are processed and the results show the presented method is efficient and practicable.
