摘　　要：蹦极是从国外流行开来的一项运动,深受冒险青年的青睐。如何计算蹦极过程中他的脚踝受到的最大拉力(磅)和最大速度是本文所研究的问题。首先,根据实测数据,用二次曲线拟合出阻力与速度的关系式。之后,将蹦极的第一个周期分为两个阶段:下降无弹力阶段和有弹力阶段,分析各阶段的受力情况,根据牛顿第二定律建立非线性微分方程组,并通过四阶Runge-Kutta算法,求解非线性微分方程组,求得蹦极者的最大速度为101.34英尺/秒,脚踝受到的最大拉力为663.2磅。bungee jumping is a popular sport in foreign countries,which is popular among adventurous young people.How to calculate the maximum tension(pound)and maximum speed of his ankle during the course of bungee jumping is the problem studied in this paper.First,according to the measured data,the relation between drag and velocity is obtained by fitting the conic.Bungee jumping after the first cycle is divided into two stages:drop without elastic stage and elastic stage,every stage of the analysis of stress distribution,according to the Newton's second law to establish a nonlinear system of differential equations,and through the fourth order Runge Kutta algorithm,to solve the nonlinear differential equations,obtained by bungee jumping is the maximum speed of 101.34 feet/SEC,ankle by maximum tension is 663.2 pounds.
