冲击性加速度是人体在航空航天过程中遇到的动力因素之一,当冲击加速度超过人的耐受限度时会导致飞行员或宇航员的损伤,甚至威胁其生命安全。因此,在飞行器设计中应充分考虑人体对冲击性加速度的耐受限度,采取有效防护措施,确保乘员的身体健康和生命安全。人体对冲击加速度耐受限度的研究已经成为现代生物力学研究的焦点,本文综述该领域的研究进展。 Impact acceleration is one of the dynamic factors that the human body encounters in the aerospace process. When the impact acceleration exceeds the human tolerance limit, it will cause the pilot or astronaut to damage or even threaten the life safety. Therefore, in the design of the aircraft, the human body’s tolerance of impact acceleration should be fully taken into consideration and effective protective measures should be taken to ensure the health and safety of occupants. The body of the impact acceleration limit of tolerance has become the focus of modern biomechanics, this article reviews the research progress in this field.
