一类广义特征值问题的扰动研究

PERTURBATION RESEARCH FOR ONE TYPE OF GENERALIZED EIGENVALUE PROBLEMS

研究了实正则对<K,M>的广义特征值扰动问题。对于求解结构动力学、弹性动力学中的振动模态及分析受外界扰动后引起的谐振频率的变化都有一定的意义。

The perturbation problems of the generalized eigenvalues for a pair of real regular matrices (K, M ) is discussed. The results are very important for studying the change of resonant frequency with outside distrubing and for solving the vibrating mode for structural and elastic dynamics.
