Experimental investigation of biodynamic human body models subjected to whole-body vibration during vehicle ride.

In this study, responses of biodynamic human body models to whole-body vibration during vehicle ride were investigated. Accelerations were acquired from three different body parts, such as head, upper torso and lower torso, of 10 seated passengers during a car ride while two different road conditions were considered. The same multi-purpose vehicle was used during all experiments. Additionally, by using two widely-used biodynamic models in literature, a set of simulations were run to obtain theoretical accelerations of the models and they were compared with those obtained experimentally. To sustain a quantified comparison between experimental and theoretical approaches, root mean square acceleration and acceleration spectral density were calculated. Time and frequency responses of the models demonstrated that none of the models showed the best prediction performance of the human body behaviour in all the cases, indicating that further models are required for better prediction of the human body responses.
