Abstract
Low-frequency road surface or rail track inputs play an important role since humans are most susceptible to whole body vibration when in erect, seated backrest, forward lean postures. Therefore, biodynamic human subject modelling and simulation has been an area of key interest for the researchers in the past. The study reveals that the first lumped parameter single degree of freedom (DoF) model was considered by Cormann in 1962. Since then, several researchers investigated the influence of posture, vibration amplitudes and STH and BTH transmissibility analysis using different lumped parameter models starting from the basic single DoF to a complex 11 DoF models considering all possible human segments for the analysis. This paper acknowledges all those works carried out in the past.
