    Abstract
  • Determining the best excitation point is one of the key problems in correlation analysis. To choose the best excitation point, finite element model and a new criterion based on Mode Participation which was named coefficient of variance of mode participation criterion (CVMPC) were studied and presented. PCB case studies were presented to validate the new criterion. In the case study, the best excitation point and second best point were selected by using both CVMPC and Mode Participation method, comparison was made to show better results presented by CVMPC. The system equivalent reduction expansion process (SEREP), modal assurance criteria (MAC) and coordinate modal assurance criteria (CoMAC) were used to show the error introduced by inappropriate selection of measurement points. PCB case studies were presented to show effects of measurement points selection on correlation analysis. The case studies suggest that better results yielded by more selective picking of measurement points.
