非经典系统在自然激励下的工况模态分析

This project mainly deal with the “Operating modal analysis of nonclassical system under natural exciting” with the following 3 aspects as its major research interests:.1. Operating modal analysis and parameter identification based on natural excitation. 2. The inverse sensitivity analysis of non-classical 、non-defective and multi-variable dynamic systems. 3. Parameters identification of dynamic systems and its application for non-classical system.

本项目主要研究非经典系统在自然激励下的工况模态分析问题.针对体系非对称和载荷不可獾睦?建立一种仅利用结构在真实工况下动态相应的测量数据进行系统模态参数辨识的理论和方法,并应用到具体工程研究领域.这将为非经典系统研究开辟新途径.本研究对于工况Ｌ治黾际跫肮收险锒?运行监测,损伤评估等领域的发展,具有重大意义.
