Abstract

A tuned mass damper is a well known concept that can be used to reduce undesired oscillation of structures. In the structures where the dynamic properties are changing with time an adaptation of the tuning is needed. In this study two complementary concepts for the adaptive tuned mass damper (ATMD) were studied based on utilization of magnetorheological elastomers (MRE) and temperature sensitive elastic epoxies (EPOX). Tuning condition of the ATMD is adjusted by retaining the phase lag of the moving mass to the main structure. In addition ATMD was controlled with minimization of the response. Both ATMD concepts proved to work excellent in real scale laboratory test setup. Response of the self excited 900 kg test table was decreased approximately 60 - 80 %. The studied ATMD concept can be used in industrial and transport applications where low power consumption (few tens of watts) and short adjustment time (few seconds) are required.
