Development of vibration protection seats for agricultural machinery

Seats have been newly developed with an anti-vibration suspension system for agricultural machinery. These seats were examined in a series of laboratory tests to determine their static and dynamic physical characteristics. These seats are specifically designed for the Japanese physique. An artificial track was constructed to simulate a farm field based on BSI (British Standard) and to examine vibration the transmissibility of the seats when installed in machinery. The results indicated that the transmissibility from under the seat to on the seat in the vertical direction was approximately 0.25, although little reduction of vibration was observed in the fore-aft direction. This suggests that these seats are applicable to the agricultural field.
