Abstract:

The design problem for suppressing "ground resonance" of helicopters, with which few researchers have concerned so far, is studied in this paper. Based on the ideas of pole region placement in control thoery and of optimization the method for optimally designing the stiffness and damping parameters of the system with specified requirements is presented. The effective design criteria and procedures are presented according to the principle of "ground resonance".For illustrating the method presented in this paper three typical calculation models are studied. The results are satisfactory.
