Abstract

In this article at first the wavelet theory is described that if s advantages are informations about the location of frequencies content in the time domain, determining noises and denoising them from raw dataor process, knowing about distributaries of energy of signal at time-frequency space,... which can be used for fast computation and relatively exact analysis of structures. In following for a SDOF system of VIBRATIONa relationship between input wavelet coefficient and output (response) wavelet coefficient is provided. So with input wavelet coefficient before exact analysis the response or excited modes of VIBRATION of MDOF systems can be determinate and by facilities of WAVELET TRANSFORM, the response of system with denoising that cause lower memory occupation or how energy of process is distributed around specific scales, fast computation can be done. At the end, for demonstration of the true and accuracy of this method some examples are solved. It is nicely recommend that this method can be provided and adapted for MDOF system of VIBRATION.
