摘要
利用Stroh理论的本征方程与多自由度振动的方程非常相似特点,将Stroh理论推广到多自由度系统振动的分析研究中,获得多自由度振动的Barnett-Lothe矩阵及Barnett-Lothe积分公式,避免了求解特征值和特征向量的麻烦。
For its eigenfunctions are similar with multi-freedom vibration equations,the Stroh's theory was extended to multi-freedom vibration systems.By using the Stroh's theory,the Barnett-Lothe's Matrices and the BarnettLothe's integral formula in multi-freedom system was given,which can be obtained from M,K,C matrices.This formula avoid studying eigenvalues of vibration equations.
