| Abstract |
Railway vehicles have different traction and braking forces depending on their speed, which can be divided into constant torque areas, constant power areas and characteristic areas. The 4th order Runge-Kuta method was applied as a method for simulating these characteristics, and object model for railway vehicle was constructed using the overloading function of the function. The characteristics of the vehicle were calculated and compared with the actual values by applying the constructed model. We also calculated TPS (Train Performance Simulation) from the actual railway rail data and confirmed that it was similar to the characteristics of the actual railway vehicle. |
