Dynamic Minimum Safety Distance of Virtual Coupled Trains Based on Kinetic-potential Energy Conversion
根据安全制动模型,提出一种基于能量转换的虚拟编组列车安全防护方法.将实际项目数据作为前车的运行曲线,仿真计算了后车根据能量转换防护方法所能达到的最小安全间隔,并讨论了制动响应时间和制动能力对安全间隔的影响.结果表明,前后车的紧急制动率差异是决定安全间隔的关键因素.
In this paper,a train safety protection method based on energy conversion is proposed according to the safety braking model.Taking actual project data as the leading train's operating curve,the minimum safe distance of the following train using the energy conversion protection method is simulated.Additionally,the impact of braking response time and braking capability on the safe distance is discussed.The results indicate that the difference in emergency braking rates between the leading and following trains is the key factor of the safe distance determination.
