000001821 520__ $$2eng$$aA linear four degree-of-freedom (DOF) lumped model with 15 parameters of the human body sitting on a hard seat without a back-rest is developed in the sagittal plane (x-z plane), based on the apparent mass approach. The model is further expanded to a 19 parameters model to account for the interaction of the upper torso with a hard vertical seat back in the lumbar region. Constrained multi-parameter optimisation was performed. The measured data were fitted in the frequency range 0.5-20 Hz. Simple model structures were arrived at to simultaneously approximate measured vertical and fore-and-aft apparent masses. Developed model structures and the identified parameters can be used for further bio-dynamics research and in seating dynamics research.
