【Abstract】 On the basis of the inverse perturbation method and the formulas of parameter ε which have been developed for solving inverse eigenvalue problems by authors, the visualized interactive method for determining inverse perturbation parameter ε is introduced. It contributes to giving full play to technicians′ function and dealing with the forbidden zone problems of the frequency for the complicated engineering systems. The software realizing the method is programmed in this paper. An example shows that the method is feasible and effective.更多还原
