The (Z-V) diagram of an electric locomotive weighing 130 t is given in the Figure. a) The locomotive is operated on a route section with an application slope with a train of 300 t wagons behind it. How long does it take to increase the speed of this train from 66 km/h to 150 km/h in the exit direction? b) Calculate the load that the locomotive can pull on this route (in the exit direction) at 150 km/h regime speed. Data: specific resistance W0=2+ V2/4000 kg/t will be calculated by the relation 1000(1+E)/g=100 will be taken. The speed range will be selected at most 20 km/h.

Question
The (Z-V) diagram of an electric locomotive weighing 130 t is given in the Figure.
a) The locomotive is operated on a route section with an application slope with a train of 300 t wagons behind it. How long does it take to increase the speed of this train from 66 km/h to 150 km/h in the exit direction?
b) Calculate the load that the locomotive can pull on this route (in the exit direction) at 150 km/h regime speed.
Data:
- specific resistance W0=2+ V2/4000 kg/t will be calculated by the relation
- 1000(1+E)/g=100 will be taken.
-
The speed range will be selected at most 20 km/h.
