人体下肢承受墩撞冲击破坏特性的模拟计算
Impact characteristic simulation calculation of human lower limb under the impact loading
【摘要】 根据人体测量学参数建立具有骨骼和关节的人体冲击动力学参数模型,对模拟矿井墩罐事故中人体下肢各部位(足、膝、髋)的瞬时冲击载荷进行了分析计算,对人体不同下坠速度情况下所受到的冲击损伤进行评估.改变人体下肢站立姿态,通过与正常站立姿态所受载荷对比发现,下肢略有弯曲的站立姿态对于减少冲击载荷有较好的效果.以此结论预测,在事故发生时适当弯曲下肢可以起到较好的减缓冲击载荷的作用.
【Abstract】 A human impact dynamic parameter model was developed based on anthropometry data in order to obtain the mechanics characteristic of human lower limb under impact loading.Human lower limb was calculated under the different contact velocity and different joint bend angles.The impact loading data of hip,knee and foot were gotten from the similar analysis based on emulational software.Propriety bend angle of joint can reduce the impact force and increase the contact time,which can decrease the hurt of joint and bone.
