wavelet analysis - Opis:
- The paper presents the test procedure for determining dynamic parameters of mechanical structures, by using the method of wavelet analysis of vibration signals as a response of the construction to impulse excitation. Basic mathematical foundations have been shown for a mechanical system with one degree of freedom and its generalization for mechanical systems with many degrees of freedom. The correct functioning of the programme, which is the implementation of procedure for the MATLAB platform, has been tested with the help of programmable simulation of vibration signals and sinusoidal mechanical signals. The author has presented the results of the identification of dynamic parameters of two, selected mechanical structures: a free hanging steel plate and an acoustic screen. The results have been verified by comparing them with those obtained by modal analysis.
