Abstract:
Various vertebrae taken from 34 cadavers were tested separately on a Schenck tester with static and dynamic loads to evaluate their strengths. For an impact lasting for a relatively long period, the tolerance of each vertebra is under 21 G. Through an electronic model of human spine based on its dynamic characteristics under the impact of an opening parachute, an allowable magnitude of impact was estimated as 25 G for 50 ms. This data might be of use for our aviation industry.
