  6. A method is proposed for the parameter identification of the viscoelastic internal dampers of the multirotor systems in this paper. the multi - rotor system is regarded as a composite structure. the impedance matching method in the substructure method for structural dynamic analysis is used for the dynamic calculation of the structure. the augmented lagrange method is applied to the iteration calculations of the characteristic determinant of eigenvalve equation of the system. and then the results of parameter identification can be obtained. upon the dynamic characteristics of the system, the method can reveal the influence of the gyroscopic moments of force precisely. in process of the analysis, the various properties of multi - rotor systems are made the best use of, so the measure of the modes parameters is avoided, the calculation is simplified. in addition, an efficient method is proposed to establish a dynamic model of multirotor systems with viscoelastic internal dampers. the calculating results are consistent with the experimental results satisfactorily
