摘要
针对飞机着陆撞击时人体的冲击响应问题,采用11自由度坐姿人体动力学模型,研究了从座椅到人体关键部位的振动传递率,并计算分析了坐姿人体在受到垂直方向上的冲击激励时的冲击响应。结果表明在飞机着陆撞击过程中,人体的腰椎响应较大,容易造成损伤,座椅对人体的支持刚度在冲击过程中对人体的冲击响应有较大影响,设计适当的座椅支持刚度可以减小人体的冲击响应。
The impact responses of human body during aircraft force-landing was aimed at by studying the seat-to-body transmissibility on a 11-DOF seated human body model.The impact responses of human body under the vertical impact excitation were examined by numerical simulation approach.The results show that the lumbar spine would be more easily injured than the other parts of the body because of more evident response.Moreover,it is indicated that the passenger seat stiffness is of obvious influence on the responses of the human body under vertical impact excitation and the appropriate design of the passenger seat stiffness can reduce the impact responses of human body significantly.
