Development Vibrations

Large piston engines produce power in short pulses and from as many as 24 cylinders. At worst, when they excite resonances, the resulting vibrations can be highly destructive. Attenuating vibrations when mounting engines and driven equipment is the special challenge taken up by scientists at the VTT Technical Research Centre of Finland.

Mass damping for vibration control

A tuned mass damper is a well known concept that can be used to reduce undesired oscillations in structures. However, for structures where the dynamic properties are difficult to estimate, a traditional mass damper needs to be designed very carefully to make it work effectively [1, 2, 3, and 4]. For these kinds of structures, an adjustable tuned mass damper (ATMD) is an effective vibration control tool.

The reliability of diesel generators can be increased if their vibration levels can be reduced. Tuned mass dampers have been used to reduce the vibration of diesel engines and generators [5, 6]. Moreover, more complex...
