This paper combines the concepts of substructure analysis and group-the- oretic methods to treat the partially symmetric structures. It points out that if the generalized displacements on the basis vector in irreducible subspaces are taken as unknown bariabales then the original displacement space can be divi- ded into a series of uncoupled displacement subspaces even for the substruc- ture condensation problems. For each subproblem the triangularzation of the internal global matrix as well as the...

This paper combines the concepts of substructure analysis and group-the- oretic methods to treat the partially symmetric structures. It points out that if the generalized displacements on the basis vector in irreducible subspaces are taken as unknown bariabales then the original displacement space can be divi- ded into a series of uncoupled displacement subspaces even for the substruc- ture condensation problems. For each subproblem the triangularzation of the internal global matrix as well as the condensation of the external stiffness ma- trix can be carried out individually. The transformation to the external stiff- ness matrix represented in terms of the original displacements is also descri- bed. It is proved that only the elements relating to the deiplacements in the basic region are necessary to be calculated. This method increases the computational e fficiency enormously in compari- son with the ordinary repeated substructuring method.

本文指出对称子结构模式的内部阵与出口阵可按各子问题分别进行三角化与凝 聚,同时给出了各子问题的出口刚度阵与原位移基底上的出口刚度阵之间的转换关 系,从而使群论的方法应用于更为广泛的、只具有部分对称的结构分析成为完全可 能。与普通的重复子结构方法相比,本文给出的方法在计算速度上有量级的提高。

This paper combines the concepts of substructure analysis and group-theoretic methods to treat partially symmetric structures. It points out that if generalized displacements on the basis vectors in irreducible subspaces are taken as unknown variables then the original displacement space can be divided into a series of uncoupled displacement subspaces even for the substructure condensation problems.

This paper combines the concepts of substructure analysis and group-theoretic methods to treat partially symmetric structures. It points out that if generalized displacements on the basis vectors in irreducible subspaces are taken as unknown variables then the original displacement space can be divided into a series of uncoupled displacement subspaces even for the substructure condensation problems. For each sub-problem triangularization of the internal global matrix as well as the condensation of the external stiffness matrix can be carried out individually. The combination of these-condensed external stiffness matrices is just the external stiffness matrix of this substructure to the generalized displacements. The transformation to the external stiffness matrix represented in terms of the original displacements is also described. It is proved that only the elements relating to the displacements in the basic region need be calculated.This method increases the computational efficiency enormously in comparison with the ordinary repeated substructuring method.

本文把群论方法与子结构分析的概念结合在一起,处理部分对称结构的分析问题,对于不可约基矢上的广义位移,文中指出了任何一个对称子结构模式的内部阵的三角化以及出口阵的凝聚都可以分成一系列子问题单独地进行。文中还给出了从各子问题的凝聚出口阵回到原位移基底上的凝聚出口阵的一种简化后的转换关系,从而使计算工作量又得到进一步缩减。 与普通的重复子结构方法相比,本文给出的方法在计算速度上有大幅度地提高。

A new element-type method for modifying finite-element models is developed by using the practical complete mode set as reference basis. The mode set is essentially constructed by measured normal modes and high order analytical modes. Thus, although the method only utilizes the orthogonality condition of the eigenvectors with respect to the mass and stiffness matrices, the modified model will meet the eigenequation. Because the reference basis contains the high order analytic modes, the updated mass and stiffness...

A new element-type method for modifying finite-element models is developed by using the practical complete mode set as reference basis. The mode set is essentially constructed by measured normal modes and high order analytical modes. Thus, although the method only utilizes the orthogonality condition of the eigenvectors with respect to the mass and stiffness matrices, the modified model will meet the eigenequation. Because the reference basis contains the high order analytic modes, the updated mass and stiffness matrices are guaranteed to reproduce the measured eigen-pairs and high order analytic eigen-pairs. In addition, the modified model obtained by the method will also retains the physical significance of parameters of original displacement-FEM, hence the present model is called as "Compatible Modified Model".

本文建立了一种"一致元素型法".由此方法得到的"相容修正模型"不仅是唯一的,而且仅依赖正交关系导出便能满足特征方程.另外,由于本方法又属于"元素型"模式,所以相容模型有能较好地逼近位移有限元模型的特点.总之,本方法既克服了"引言"所述其它方法存在的三个问题,又具有比较简单的修正公式.
