摘　　要：加速度作为蹦极设计的一个重要指标,其大小直接关系弹跳者的生命安全。在蹦极运行特性分析的基础上,应用机械能守恒原理和胡克定律,详细推导了蹦极加速度方程。以国内某景区高空蹦极为例,采用瞬态动力学仿真分析技术,分别求出在6种弹跳者体重工况下,蹦极加速度的仿真结果,并对加速度仿真结果和解析结果进行对比,借助蹦极方面的相关标准规范,对蹦极加速度进行评价分析。分析结果表明,仿真结果与解析结果的最大误差小于1%,表明了仿真结果的可靠性;弹性绳的伸长倍数决定蹦极加速度范围,理论加速度的范围为2.67 g~3.33 g。该研究方法对蹦极的安全性设计和加速度的校核计算具有一定的参考和工程应用价值。As an important parameter in design of bungee jumping,the acceleration is directly correlated with passenger safety.Through the analysis of bungee operation characteristics,this study derives the bungee acceleration equation in detail by applying the principle of conservation of mechanical energy and Hooke's law.By employing transient dynamics simulation analysis technology,the simulation results of bungee acceleration are obtained for six different passenger weight conditions,using domestic bungee as an example.These simulation results are then compared with the analytical results and evaluated against relevant standard bungee acceleration.The analysis results reveals that the maximum error between the simulation and the analytical results is less than 1%,affirming the reliability of the simulation results.Furthermore,the extension multiple of elastic rope determines the acceleration range of bungee,which is theoretically estimated to be between 2.67 g~3.33 g.This research methodology provides valuable insights and practical implications for the safety design and acceleration calculation of bungee jumping.
