摘　　要：针对载人探月飞船半弹道式再入时人体姿态对动态响应影响明显,通过载人离心机模拟飞船半弹道式返回再入大气层过载曲线,对比分析躺姿和卧姿状态下之五十百分位HybirdⅢ生物力学假人头部、胸部及臀部力学响应的差异。结果发现:2种姿态下假人的头部、胸部、臀部合加速度响应与输入基本一致,且以胸背向响应为主;卧姿状态下头部响应的+Gz分量较高,且从头部至臀部依次降低;躺姿状态下头盆向载荷的传递可以忽略不计。研究结果可为加速度防护人体姿态设置提供依据。The dynamic response will be significantly influenced by the posture of human body during semi-ballistic trajectory re-entry of the lunar spacecraft.To provide basis for the selection of body posture against acceleration,the manned centrifugal was used to simulate the acceleration loads of spacecraft during semi-ballistic trajectory re-entry,and the 50th male HybridⅢdummy as human body surrogate were exposed to the re-entry acceleration.Then the dummy acceleration responses in lying position and the supine position at the head,chest and lumbar were obtained and analyzed.The results showed that the acceleration responses at the head,the chest and the lumbar of the dummy were basically consistent with the input load under both body positions,and the human responses in the chest-back direction were predominant.The+Gz response at the head was the highest among other body segments,and the ranking of+Gz responses were the head,the chest and the lumbar in supine position.However,the load transfer in Gz direction could be neglected in lying position.The results may serve as a reference for selecting the body position during semi-ballistic trajectory re-entry.
