STUDY OF THE OWNER RESPONSE OF THE HUMAN BODY UNDER THE VERTICAL VIBRATIONS ACTION INTO A VEHICLE

Abstract

This paper presents some aspects about the dynamic response of the human body subjected to the vertical harmonic vibration in the travel inside the auto vehicle. There is a model presented in the specialized literature. This is transformed for the given study because is necessary to realize the vertical vibration along the human body axis. The human body has the owner pulsations (eigenvalues) that we solved in another paper, and here we try to obtain the displacements of the body elements near by these pulsations. This motion is considered a harmonically action force produced by the vehicle seat. There are two different studies:  using a linear lumped parameter systems seat – human body model.  using a nonlinear lumped parameter systems seat-human body model.
