Examples involving longitudinal vibration of a bar and flexural vibration of a simply supported beam subjected to harmonic and impact loading are analyzed.
However, due to the removal of the unmodelled harmonics, the impact of the truncation is much greater in the experimental MSE (pink inverted triangles).
For example, there are sub-harmonic, multi-impact, periodic orbits and chaotic, steady state responses.
The effect of the time differentiation of the signal is to decrease the amplitude of the lower-order harmonics with little impact on the higher harmonics.
The verification procedure involves three parts: natural frequencies, harmonic spectra and impact responses.
In this paper, non-smooth dynamics of two elastic beams excited by harmonic force with impact interaction is studied through analyses, simulations, and experiments.
This paper reports on the investigation of the in-plane behaviour of the mortar-free structures under different loadings: push over, snap back, impact, harmonic and earthquake loadings.
Constant-gain negative velocity feedback, Lyapunov feedback as well as a linear quadratic regulator (LQR) approach have been used for active vibration control with the structures subjected to impact, harmonic and random excitations.
Smaller signal peaks right of center frequency F c are positive harmonics of the impact frequencies.
More specifically, these studies concentrate on load profiles, system losses, voltage profiles, phase unbalance, harmonic and stability impacts.
