"Good Vibrations": a complete software solution for experimental, operational modal analysis and operating deflection shapes

Abstract

This paper gives a complete overview about a new software for structural analysis. The software "Good Vibrations" is an innovative program for the calculation of vibrational properties of mechanical structures and buildings by means of the known methods of experimental (with selective excitation), operational (stochastic or environmental stimulus) modal analysis and operating deflection shapes (under given operating situations). Here, the vibrational properties are characterized by the modal parameters: natural frequencies, damping, mode shapes (deformation). Currently, it is the only software on the market that offers this comprehensive combination of algorithms. The results of structural analysis can be used directly for vibration analysis / optimization, to improve the associated FE (Finite Element)-model or for vibration based Structural Health Monitoring.
