【Abstract】 Generalized modes method of defective systems for eigenvector sensitivity analysis is presented.It is proposed to establish a feature space about generalized modes by using the theory of generalized modes for sensitivity analysis in linear vibration defective systems which does not possess a complete set of eigenvectors in N-space.Simultaneously a brief and rapid algorithm is introduced to calculate the coefficients of the power series expression of generalized modes by gradual and recursive solution.A numerical example is provided to illustrate the accuracy and efficiency of the algorithms.更多还原
