“…The rod length is l = 1500 mm. The second natural frequency of the longitudinal oscillations (according to formula [3]) is f2 = 3459 Hz (taken as an example). The right edge of the rod is driven at this frequency through the fastening; the harmonic wave will propagate along the rod with the same speed as in the rod with free ends.…”

“…According to analytical formula [3], the first four natural fluctuation frequencies of the rod fixed at the ends of l = 1500 mm length, are identified: f1 = 1729 Hz, f2 = 3459 Hz, f3 = 5188 Hz, f4 = 6198 Hz.…”

“…The problems of using mathematical modelling techniques for research of physical processes in rod elements under the influence of a short-term shock pulse are considered. The losses of energy in the body of the rod are not taken into account, and it is considered that the pulse keeps its shape and amplitude unchanged for all the movement along the rod [2], [3].…”

The article shows the relevance of the application of discrete models of rod structures of radio-electronic means (REM) for the study of their behaviour under transient loading. A discrete model of the propagation of harmonic waves in the rod and the study of standing waves are proposed. Computational experiments using the proposed model are conducted. The results show that the model accurately reflects qualitative dynamics of the physical processes in the elastic rod while the waves of elastic deformations are passing through. The proposed models are used for software implementations of systems of mechanical simulation of the behaviour of rod structures.
