结构振型几何辨识及应用研究

Structure mode geometrical identification and application

推导了基于振型的位移、应变和应力展开公式,介绍了振型的分类方式,并根据振型的几何判别标准,分析了高宽比对结构振型的影响规律,得出了一些有价值的结论,以供参考。

The paper induces the displacement of the model of vibration, strain and stress expansion formula, introduces the classification approa- ches of the vibration mode, analyzes the influential law for the height-width ratio on the structural vibration mode according to the geometric judg- ment standard of the mode, and achieves some valuable conclusion, so as to provide some reference.
