为了研究人体对冲击加速度的响应特性,六位受试者承受了垂直冲击实验。冲击强度为3g、5g、10g。实验时测试了座椅、人体头部、胸部、腹部、肩、上臂、前臂、髂棘、大腿和小腿的加速度。人体响应的峰加速度与座椅加速度呈线性正相关。身体各部相对于座椅和髂部的传递函数曲线相似,表明身体是以一个整体对冲击进行响应的。人体共振频率随着冲击g值的提高而向左移,但主峰右移。这种人体动态响应特性,在振动与弹射人体工程学研完中也曾观察到。本研究结果为建立人体冲击模型奠定了基础。
In order to study the body’s response to impact acceleration, six subjects underwent vertical impact experiments. Impact strength of 3g, 5g, 10g. The acceleration of the seat, head, chest, abdomen, shoulder, upper arm, forearm, iliac spine, thigh and calf was tested during the experiment. The peak response of the human body is linearly and positively correlated with the acceleration of the seat. The curves of the transfer functions of the various parts of the body relative to the seat and the iliac part show that the body responds as a whole to the impact. The resonance frequency of human body shifts to the left with the increase of impact g value, but the main peak moves to the right. This dynamic response of the human body has also been observed during vibration and ejection ergonomics. The results of this study laid the foundation for the establishment of human impact model.
