Abstract: A method of measurement of the four-pole parameters of a system as a function of frequency is presented. This procedure consists of no-load dynamic measurements followed by measurements under ...

Abstract: A simple, low-cost mechanical pulse generator has numerous applications in laboratory investigations and field tests of structures. Applications may include shock tests, transient load simulations, ...

Abstract: A computer algorithm is presented for the optimum selection of a series or train of force pulses for application to a continuous system. The optimized pulse train generates oscillations in a ...
