Abstract
In this paper, an experimental technique is introduced to investigate the structural response under impact loads, which consists of the waveform measuring technique in the time domain by using the WAVEVIEW software, and steady-state measurements by using the Polytec Laser Scanning Vibrometer (PLSV) in the frequency domain. The waveform measuring technique is introduced to obtain the waveform at different locations in the time domain. These experimental results can be used to verify the validity of predicted results obtained by the Acoustical Wave Propagator (AWP) technique. This PLSV technique provides an accurate and efficient tool to investigate mode shape and power flow in coupled structures. In addition, the issues related to source identification and controlling energy transfer are addressed.
