This paper contains a study of the vertical vibration modeling of the standing human body. The human body is modeled as a mechanical system consisting of a several masses connected by elastic and damping elements. A series of mechanical models, corresponding to human vibrations are presented, according to the specialized literature. The differential equations of displacements are deduced, numerically solved and the relative displacements of the human body’s elements are represented. The human body displacements depend on cinematic parameters of the platforms which vibrate. This paper ends with a series of conclusions regarding the influence of various parameters on the human body behavior exposed to vibration, on vertical direction.

Key words: human body, vibrations, biomechanical models, C program, elastic elements, damping elements
