ABSTRACT
A detailed three-dimensional nonlinear finite element model of lumbar segment L3-L5 was developed to investigate the influence of vibration on the components of human spine. The results show that the vibration effects of different spinal components are not exactly the same, and the stress near the posterior region of L4-L5 annulus is higher than that of its anterior region. The vibration exerts a great influence on the facet joint of L4-L5 segment. The changing amplitudes of stress and deformation of spine reduce by 50% on the condition that the damping ratio is 0.08.
