摘要:
该文以欧拉 -伯努利梁为模型 ,推导出基于系统响应梁的模态截断准则 ,根据模态价值大小取舍模态 ,其结论可推广到大型复杂结构系统。该法考虑了可观性向量、模态增益、结构阻尼系数及模态频率 ,较简单的频率截断法是一个很大的改进 ,降阶后的模型能很好地近似原系统性能。文末给出了一个简支梁模态截断的例子。
Abstract:
In this paper, modal reduct ion criterion is derived based on the system response taking as the model of Euler-Bernoulli beam, editing modal according to the value of modal cost s. The conclusion can be used in a large f lexible complex structure system. It is a more preferable to simpler frequency criterion, since it takes into account of f requency, v ibration mode, damping, sensor and actuator information. Reduced order model can approx imate well the basic characterist ics of the original system. An example of edit ing modal for simply-supported beam is illust rated in the end of the paper.
