1. The analysis results show that the palcement styles and the rotating angles of such a large scale deployable boom systems are functional importantly . the motions and damps of the boom systems also take importance . if motions become larger , the time for the booms to reach their spreaded states is shorter , and the impact velocities become larger , the impact accelerations become larger too
   分析结果表明，对于大尺度的伸杆机构，其布置方式和展开角度对其展开运动有重要的影响；同时也研究了铰链处外力矩对展开运动的影响，随着该力矩的增大，伸杆到达锁定状态的时间减少，碰撞时的速度增加，由此产生较大的加速度；分析了伸杆弹性和阻尼对伸杆展开过程的影响，弹性增大碰撞加速度增大，阻尼增大加速度减小，因此可将铰链处外力矩和伸杆阻尼作为伸杆展开运动调节的手段。
2. The simulation result showed that : variety of impact acceleration field has great influence on lower extremity injuries ; using safety belt has prominent efficiency to reduce lower extremity injuries ; using knee bolster with lower stiffness can reduce the loads to femur , knee and tibia ; the right foot placed on the brake pedal will increase the risk of foot injury evidently ; variety of footwell intrusion induced by impact deform of car forepart will influence lower extremity injuries severity to a certain degree
   仿真结果表明:加速度场的改变对下肢损伤有非常大的影响;佩戴安全带对降低下肢损伤风险有显著的作用;膝垫采用较低刚度的材料可以较好地降低大腿,膝部以及胫骨的受力和损伤;右脚放在刹车踏板上会使得右脚损伤风险明显加大;车体前部碰撞变形产生的脚舱侵入量对人体下肢的损伤会产生一定的影响。
