Evaluation of lumbar vertebra injury risk to the seated human body when exposed to vertical vibration

The objective of this research is to numerically determine the levels of vibration not to exceed accordingly to the corresponding dynamic stresses in the lumbar rachis when exposed to whole-body vibrations in order to identify the risk of adverse health effect to which professional heavy equipment drivers are particularly prone. A parametric finite element model of the lumbar rachis is generated in order to compute the modal parameters, the...
