实验模态分析（Experimental Modal Analysis）是以振动理论为基础，综合动态测试技术、数字信号处理和参数识别等手段，以模态参数为目标的试验，属于振动试验的一个重要分支。 模态分析试验在结构性能评价、结构动态修改和动态设计、故障诊断和状态监测以及 ...

Modal data deals with the dynamic properties of a structure and can help in the design of almost any structure, facilitating to detect areas where design changes are required. Determining the ...

John O'Callahan has written many papers over the years covering analytical model reduction techniques, structural dynamic modification, estimation of rotational dof, correlation of analytical / ...

During the ANSYS Conference & 28 th CADFEM User’s Meeting held 2010 in Aachen, Germany, a new approach was presented, which facilitates the integration of experimental modal analysis test into the CAE ...
