NUMERICAL ANALYSIS OF HUMAN SPINE DURING DIFFERENT LEVELS OF VIBRATION

Abstract

Vibrations are oscillatory movements of the mechanical system, in which displaments of points are small compared to the dimensions of the system. In transport, comfort is one of the important factors in the stady of the quality of the vehicle. It can be said that the comfort in the vehicle depends on the values and the way of transmission of vibrations to the man. After the measured values of vibrations is obtained an accurate account of deformation of the human body. In this paper we conducted measurements of the vibrations on the human body during the process of driving at different speeds. The measuremend values of vibrations are transmited to the spine of the human using a software package Ansys. Numerical analysis were determined Von Misses stresses and displaments of the spinal vertebrae driver, due to different levels of vibration.
