The Dynamic Response Index (DRI) is a measure of the likelihood of spinal damage arising from a vertical shock load such as might be encountered in a military environment (i.e., during a mine blast, or in an ejection seat). The DRI is a dimensionless number which is proportional to the maximum spinal compression suffered during the event. The DRI is derived as the solution to an equation which models the human spine as a lumped si… WebThe large inductance will limit loop bandwidth and reduce the dynamic response index.
