Truck drivers spend all day moving goods. They are exposed to vibrations every time they drive. Modern cabin suspension and an air-suspended seat already offer a high level of comfort. This, however, is designed for vertical dynamics and you can observe the cab of a truck performs large pitching vibrations during acceleration. These are examined here. A pitch model of the cabin is set up for this purpose. On the basis of this model it is examined which reduction of the vibration can be achieved by the use of a hydraulically translated vibration absorber. The advantage of this absorber is the use of the hydraulic transmission to reduce the heavy mass at high absorber inertia. 4 kg of fluid mass act as 131 kg absorber mass reducing vibrations by more than 10%. The conventional vibration absorber is inacceptable due to the additional load. The investigation based on VDI 2057 Part 1 shows that driving comfort can be increased.
