【摘要】 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。更多还原

【Abstract】 In order to study the characteristics of human body responding to impact acceleration,6 subjects were exposed to vertical impact.The strength of impact were 3g,5g and 10 g,Acceleration data on seat,head,shoulder,iliac crest,arms and legs were measured.The peak values of acceleration displayed a positive linear correlation.The characteristics of different parts of human body responding to seat and ilium were substantially the same It showed that human body responded to impact as a whole,With increasing impact gs,the resonance frequencies of human body moved to left-side,but the main resonance peaks moved to right-side.Such dynamic response characteristics had been observed in our previous vibration tests.The results of this study might provide a basis for developing an impact model.更多还原
