Three-dimensional modelling and parameter identification of the seated human body exposed to random vibration

The paper deals with the modelling and parameter identification of the human body in a sitting posture. The advantage of this paper is to announce a simplified, but also a reliable three-mass model representing dynamic behaviour of the main human body parts, i.e. pelvis, torso and head. Their equivalent masses are interconnected by classical mechanical constraints in the form of springs and dampers. The stiffness and damping coefficients are identified by means of an original optimisation procedure that is used to minimise the error between measurement and simulation results. The model is proposed to be used for simulation studies of vibration-induced effects on the human body as well as for defining a specific vibration-isolation properties of automotive seat suspension systems with minimal computing cost and time.
