摘要
传统的定载吸能器以50百分位男性乘员满足95％生存率为条件设计,它不能为全体乘员提供保护,变载吸能器能够根据乘员重量而调节动作载荷,为全体乘员提供最合理的保护,同时可以大大降低吸能器的冲击行程。
Conventional fixed-load energy absorbers are designed for the 50-pecentile male weight under the crash condition of the 95-pecentile survivable accident and could perform inefficiently at the extremes of the occupant weights spectrum. Variable-load energy absorbers make it possible for the limit load of an energy-absorbing seat to correspond to the occupant' s weight, providing optimum crash protection within the available stroking in the aircraft. Contrasted with fixed-load energy absorbers, Variable-load energy absorbers can reduce the stroking distance significantly.
