“…This leads to some injuries like spinal disorder, weakness in sight, pain in internal tissues and heart problems in a long term. Many researchers studied about human body responses to vibration, and how they can minimize the negative effects of shock to human body [1][2][3][4][5][6]. The responses have been assessed in terms of the apparent mass, driving point impedance and transmissibility.…”

Passenger seat is main part of vehicle which has direct effect on transmitted vibration to the body. Seat suspension can remove unwanted and harmful vibration if right parameters were selected. Each human body organs has specific natural frequency. When vehicle vibration reaches to this frequency range, resonance will occur, and this phenomenon is harmful in long term. Usually lumped models were used to predict human body response to vibration. In this paper, via Qassem biodynamic model, the relative displacement of lumbar spine seat to spine vibration transmissibility was minimized by artificial neural network method. By this technique, optimal spring constant and damping coefficient were found and verified.
