Integrated Fluid Dynamic Vibration Absorber for Mobile Applications

The setup of a suspension always leads to a compromise between comfort and safety. In order to counteract this in a passive approach, one could attach a structural extension in the form of a dynamic vibration absorber to the axle. Thus, energy of the wheel vibrations is diverted into the vibration absorber instead of the body. In comparison to a classic dynamic vibration absorber, which is not in the sense of lightweight construction due to the additional mass, our Fluid Dynamic Vibration Absorber (FDVA) reduces the dynamic mass by using a hydrostatic transmission.
