摘　　要：介绍人体蹦极的基本物理过程,并在理论上根据模型列出方程,从而刻画出人体蹦极的运动轨迹,探究人体蹦极整个过程中不同物理量的变化及影响因素。利用Matlab对其求解析解,并计算一系列不同弹性系数的蹦极绳拉伸造成的影响,定量分析人体在此过程中的各物理参量变化,从而计算出给定条件下的极限安全防护装置的弹性系数。同时,对人体蹦极过程进行仿真,通过对不同物理量变化的模拟,直观展示人体蹦极整个过程,并通过对比仿真结果,对给定条件下人体是否处于安全状态进行判断。Basic physics of the bungee jumping and in theory correlation equation was listed according to the Newton＇s law, the establishment of bungee jumping trajectory model, exploring people bungee jumping when the whole process of different physical quantities change and influence factors. Of Physics Formulas for the analytic solution by Matlab, calculation of a series of different elastic coefficient of the bungee cord, quantitative analysis in bungee jumping process by force change, obtained under given conditions, the limit of safety protection device of elastic coefficient. At the same time, motion trajectory of bungee jumping process of simulation, through the simulation of different physical quantities change, visual display of bungee jumping the Process and by comparing the simulation results, under the given conditions is in safe state is judged, the research of security of the bungee jumping has certain reference value.
