Frequency characteristics of a dynamical system at force excitation

Abstract

Frequency response functions are important characteristics. They define the properties of a dynamic system. Preferably they are used mainly for solving problems in the frequency domain. They are linked to the choice of computational model and to the means of structure excitation. They are complex characteristics, so have their amplitude and phase components. They may be obtained in different ways. Some possibilities of calculating at force excitation are discussed in this paper.
