Popis: A tuned mass damper is a well-known concept that can be used to reduce undesired oscillation of structures. However, structures where the dynamic properties are difficult to estimate traditional mass damper need to be designed very carefully to make it work properly. For these kinds of structures an adjustable tuned mass damper (ATMD) is an effective vibration control tool. In this study a simple concept for the ATMD was studied based on a leaf spring and moving mass. Aim of the concept was to make a simple low cost solution with wide control range. The ATMD can be used as a troubleshooting device with structures that have resonance problem without extinctive pre study of the structure. Moving mass and span length can be varied easily so the adjusting of the ATMD can be done in situ. All the parts in ATMD are steel so the temperature range is wide and also the reliability is good. The studied ATMD concept was designed to use in generator part of a diesel generator set. The ATMD can also be used for example in other engine, manufacturing and transport applications.
