The Crew Seat Vibration Test and Analysis to a Special Vehicle

Abstract

This paper tested and analyzed the vibration of a special vehicle’s crew seat, collected the vehicle cabin vibration signal under different road environment, and at certain speed, it studied the effect of vehicle vibration on crew, and as the basis of vehicle seat retrofit design. The analysis results show that the maximum vibration acceleration value was on the longitudinal of the driver and other crew’s position, and in the later, design improvements should mainly focus on the longitudinal vibration reduction. At the same time in the process of vehicle test under different grade road crew’s comfort, all performed well; this shows that design in a certain velocity of anti-vibration meets the requirements of ergonomics. This paper provides suitable personnel vibration fatigue monitoring test method for special vehicle crew; the data obtained from this method are significant and can be effectively applied to the practical test, and it has important reference value on the seat of the vehicle vibration reduction design and the crew comfort evaluation.
