| Bibliography: | 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. bungee jumping; simulation ; spring; safety coefficient CHEN Cheng a, DENG Ke-ya b, WANG |
