Evaluation of vibrations transmissibility in vertical direction using biomechanical modeling of human body for the seated posture

In the current manuscript, a novel biomechanical model of human body is proposed for evaluating the biodynamic responses to vertical vibrations and vibration transmissibility for the seated position with ignoring backrest support. In this regard, the 6-DoF lumped-parameter model with six concentrated masses which are connected using several linear springs and dampers is presented.Further, the full vehicle model and passenger’s seat is developed in ADAMS/CAR in order to utilize the acceleration of seat under a road excitation. It should be noted that the resultant data of ADAMS/CAR model are served as inputs of biomechanical model of human body to achieve the transmissibility for all parts of human body.
