对薄壁梁迁移矩阵算法的一点改进

An Improvement on the Transfer Matrix Method for Thin-Walled Beams

针对基于薄壁梁理论所导出的弯扭耦合振动微分方程的特点，经将剖面状态矢量的分量适当排序后，借助矩阵分块技巧，大幅度地缩短了生成场迁移矩阵的计算时间，从而可以显著地提高应用迁移矩阵法对薄壁结构进行弯扭耦合振动分析计算的效率．

After the components of the state vector are collated properly according to the characteristics of the bending-torsion-coupled vibration equations deduced by the thin-walled beam theory,the calculation time to generate the field-transfer matrix is reduced considerably with the help of matrix-partitioning technique,thereby the efficiency of analyzing bending-torsion-coupled vibration with transfer matrix method is promoted obviously.
