Abstract:
A laser–Doppler vibrometer was used to detect gated harmonic surface waves traveling along a steel block, together with their reflections from a rectangular plate attached to the block through a viscous couplant. A signal demodulator was designed to allow visualization of the waves on an oscilloscope, and computer data acquisition was performed. Using various plates and couplants, curves showing the reflected/incident power ratio as a function of the wavelength were obtained and compared with those obtained from a previous theoretical analysis. The correlation between the positions, number, and amplitudes of the resonances obtained from experiment and theory was analyzed, as was the influence of the couplant.
