Abstract: This paper studies the direct effects of acceleration transmissibility between the head and seat of the driver, such as driver mass. The six DOF, seat-driver vibration model, is considered. A refuse truck with a specific driving cycle for 20 minutes is selected to evaluate the horizontal driver vibrations. The horizontal acceleration used on the driver is due to acceleration and braking operations, and the amount is considered based on the root mean square of the vibration transfer function for 20 minutes. Besides, suitable values of the vibration parameters are obtained according to the driver mass to minimise the horizontal acceleration. A survey conducted shows that the damping coefficient between the lower part of the driver's body and seat the most effect on the horizontal acceleration acting on the driver. A linear relation between driver mass and backrest parameters and seat pan derived. Also, polynomial equations between driver mass, seat pan, and backrest derived.

Keywords: refuse truck; horizontal acceleration; vibration transmissibility; parameter study.
