Analysis of detection of mass position using the change of the structural dynamic characteristics

동특성 변화로부터 구조물의 변경질량 위치 해석

This study proposed the analysis of mass position detection due to the change of the mass and stiffness of structure by using the original and modified dynamic characteristics. The method is applied to examples of a cantilever and 3 degree of freedom by modifying the mass. The predicted detection of mass positions and magnitudes are in good agreement with these from the structural reanalysis using the modified mass.
