Impact Force Identification by Using Modal Transformation Method in Collocated and Non-Collocated Cases

Considering the impact location is inaccessible, impact force determination by using remote responses away from the impact location must be developed. A methodology utilizing operating deflection shape (ODS) analysis, modal analysis (MA) and modal transformation method (MTM) to evaluate the dynamic...
