000022758 520__ $$2eng$$aUndesirable vibration level of construction parts is a dangerous and unwanted phenomenon in the modern engineering which can potentially lead to damage or destruction of a construction component. In some cases, this issue can appear in already constructed constructions where additional reducing of the vibration level is a required operation. This reducing can be performed by dynamic parameters modification to avoid the resonance states or to increase the ratio of damping of competent structure modes. This work is aimed to presentation of modal synthesis application to desired modification of dynamic parameters of a structure to decrease the level of its vibration. It includes the theory of modal synthesis in case of original and modifying structures and the demonstration example of the the cantilever beam modified by aluminum foam structures in appropriate places to reach the desired modal and spectral parameters.
