Dynamic Minimum Safety Distance of Virtual Coupled Trains Based on Kinetic-potential Energy Conversion

Abstract:

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.
