  • A general method based on RICCATI transfer matrix is presented to calculate the 2nd order perturbations of eigendatas for one-dimensional structural system with parameter uncertainties.The method is applicable to both real and complex eigendatas of any one-dimensional structural system.The formulas for calculating the sensitivity derivatives of eigendatas based on this method are also pre sented.The method is applied to the perturbation analysis for the eigendatas of a rotor with gyroscopic moment,and the differences between the perturbation results and the accurate calculating results are small.
