Seat Dynamics and Passenger Comfort

Abstract

The influence of the characteristics of the vibration input, the seat and the seat occupant on the transmissibility of vertical vibration through railway seat cushions has been investigated. Seat characteristics were found to have a larger effect on transmissibility than occupant or vibration characteristics. Laboratory measurement of the transmissibilities of ten different seat cushions demonstrated that if the cushions were fitted into vehicles, the occupant would receive significantly different rides. The need for standardized dynamic testing of vehicle seating is identified.
