Steady Vibration Wave Form of a System Subject to Periodic Excitation

Abstract

In this report, we have studied a method to predict vibration wave form of a system subject to certain periodic excitation with estimation of excitation wave form using the steady state vibration analysis by convolution integral. For example, we used a beam system subject to electromagnet excitation. First , we measured vibration wave form at a certain point on the beam and derived the excitation wave form from it. Next, we predicted vibration wave form at another point using the derived excitation. As a result, agreement of the predicted vibration wave form and the experimental one was shown.
