A pulse-shaping technique based on a short, finite Fourier series expression for the forcing function is shown to attenuate residual dynamic response in elastic systems by several orders of magnitude. The approach is based on selecting the Fourier coefficients to depress the envelope of the residual response spectrum in desired regions. Response spectra comparisons are made for the rectangular, double versine, and shaped pulses.
