TASKS OF THE MODAL TEST AND REPRODUCTION OF FORCES BY MEANS OF ELECTROMECHANICAL SIMULATION

The main problems of ground-based experiments aimed at identifying modal characteristics and reproduction of force impacts are discussed. The latter has a lot of similarity in terms of the hardware and software used. The issues concerning boundary conditions, influence of excitation means on aircraft construction, and aerodynamic forces that arise in preparation for aircraft ground-based experiments are discussed, and several solutions to these issues are suggested in this article.
