AN ELECTRICAL IMPULSE LOADING DEVICE FOR THE DYNAMIC ANALYSIS OF STRUCTURES

Abstract

In linear systems analysis, it is considered that an impulse whose duration is less than one cycle of the highest natural frequency of the system is a good approximation to an ideal impulse function, whose spectrum contains equal amplitudes of all frequencies. With such an excitation all of the natural frequencies impulse technique is quite convenient of the system are excited simultaneously [l]. The and accurate for measuring the natural frequencies of vibration of the system.
