Damping requirement of a suspension seat subject to low frequency vehicle vibration and shock

Vibration attenuation performance characteristics of a suspension seat are investigated under excitations arising from different road and off-road vehicles. A Two-Degrees-of-Freedom (2-DOF) model of the suspension seat is formulated upon integration of component models, and consideration of the end-stop impacts and potential body-hop motions. Validated analytical model is applied to identify the desirable damping parameters, to achieve improved attenuation of continuous and transient vibration of varying intensities. The results, suggest that a suspension design with relatively higher compression and rebound mode damping would be desirable for realising improved shock and vibration isolation performance for vehicles with predominantly low frequency ride vibration.
