Dynamic Parameters Tuning Using Structural Dynamic Modification

Significant vibration of construction components are unwanted and dangerous problems in the modern engineering. Nevertheless, undesirable levels of vibration can occur in already existing constructions. Therefore, additional modal and spectral parameter modification, to reach the desired vibration reducing, is required. This work presents structural dynamic modification methodology that allows the modal properties of a structure to be effectively changed. As the demonstration of this method, the example of a cantilever beam structure modified by aluminium foam layer elements was chosen. This example represents inertial, stiffness and damping modification aimed to tuning of modal and spectral parameters of the original structure.
Keywords: dynamic parameters tuning; structural dynamic modification; aluminium foam.
