Prediction of Structural Modified Design Parameter due to the Change of Dynamic Characteristic

동특성변화에 따른 구조물의 변경된 설계파라미터 예측

This study proposed the analysis of mass position detection and modified stiffness 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 agrement with these from the structural reanalysis using the modified mass.
