主动质量控制系统的权矩阵选择及其参数的敏感性分析
|
摘要
在主动质量控制系统(AMD)中,权矩阵的选择对受控结构的地震反应控制是非常重要的。采用相对位移控制方式时,虽然结构的相对位移能够得到有效控制,但个别层的层间位移可能被放大了。这种现象对结构来说是非常不利的。本文针对这种情况提出了一种新的权矩阵选择方法。该方法不仅可减少结构各层的相对位移,而且,对结构各层的层间位移的控制有很强的针对性。最后,本文还对权矩阵、AMD参数以及结构参数对控制效果的影响进行了较为详细的分析,得到了一些有意义的结论。
The selection of weight matrix and sensitivity analysis of parameters in active mass damper is performed. A new method to select the weight matrix is proposed in this paper. It is based on the story drift to form the structural vibration equations. It is in different with the results based on the relative displacement. It is shown that not only reduces the story drift but the relative displacements. It is found that the influences of weight matrix and the parameters of both AMD and structure on the control effects are discussed in detail. It is some useful conclusion that is obtained through the study.
