Measure for extinguishing vertical vibrations on the seat of a wheel tractor when moving along a random profile of the path

Various measures of damping vertical vibrations on the seat of a wheeled tractor when driving along a random path profile are analysed. The distribution of vibration frequencies over the structural elements of a wheeled tractor is given. A device has been developed and manufactured to ensure the verticality of the operator’s seat. The seat damper device has been experimentally studied, while the efficiency of using dynamic vertical vibration dampers in the seat cushioning system, which provide vibration damping at transport and technological tractor speeds of 5…35 km/h on unequal roads with natural surface.
