Authors Abstract
Content
The human body is most sensitive to low frequency whole body vibrations. Ride vibrations of off-road vehicles, caused primarily by irregular terrains, predominate in the 0.5 - 5 Hz frequency range. A suspension seat offers the simplest means to improve vehicle ride by reducing ride vibrations transmitted to the driver. A computer model of an off-road vehicle suspension seat was developed which can aid the designer in the selection of optimal suspension parameters. A parametric study was performed to determine the frequency response characteristics of the validated suspension model via computer simulation to investigate the influence of suspension parameters on the vibration transmission performance of suspension seats.
