Using three dimensional finite element model of the human brain, vibratory characteristics of the human brain according to vibratory direction was analyzed. From this analysis 9, 14Hz and 2, 3Hz natural frequencies were calculated for adult’s and baby’s brain model respectively. Regardless of the vibratory direction relatively high shear stress, pressure and von Mises stress variation except acceleration were detected in the baby brain model. At each natural frequencies, adult’s model showed relatively high stress level in the region of lower limb control area compared with upper limb control area at 14Hz natural frequency.
