THE MECHANICAL BEHAVIOR AND THE MATHEMATICAL MODELING IN THE CASE OF THE VIBRATIONS INDUCED TO THE SPINE

Abstract

Back injuries, especially lower back pain, are amongst the most prevalent and costly non-lethal medical conditions affecting adults. An association between vehicle whole body vibration exposure and the development of lower back pain has been established through numerous epidemiological studies. In this paper we present a concept which could absorb the vibrations that appear at the driver or the passenger of a car or bus. To protect and prevent the lower back pains generated by the car vibrations and the rough road we construct a vibroisolator that can be inserted in the seats. Under those circumstances the following actions are required: the control, adjustment of the vibrations, their extinction, absorption or isolation – through vibro-isolation systems – environment protection, of real estate property and machines, the capture (absorption) of the vibrations, regularization and automated control of the sources by instruments of measure and control.
