摘　　要：本文对上肢在高速气流吹袭下的致伤机理进行了分析,提供了计算稳态弹射时上肢防护约束力的约束方程组。根据这一约束方程组,我们计算了在握扶手和拉中央环两种弹射姿态下,上肢的最小约束力。计算结果表明,上肢的最小约束力的施加部位在临近肘关节和腕关节的上方不远处。文章最后讨论了对上肢防护装置的要求,以及上肢挡臂板的设计和最佳弹射姿态问题。The mechanism of upper limb injury by windblast was analysed. The constraining equation for steady states were established. The value of constraining forces needed for aircrew windblast protective devices of upper limb at steady—state ejection were calculated with these equations. The lowest constraining forces needed for upper limb were calculated under the configurations of hands of top of the thighs and hands on alternate firing handle. The results showed that the optimal location to exert minimal constraining forces on upper limb is close to the elbow joint and carpus joint.The requirements for the aircrew windblast protective devices of upper limb, the design of arm—restraint plate and optimum ejection attitude were also discussed.
