Abstract
The utility model discloses a flywheel apparatus capable of simulating heavy-load starting of a locomotive. The flywheel apparatus comprises a contact electrical network, a locomotive and a testing stand. A traction motor and locomotive wheel pairs are arranged under the locomotive. One side of the testing stand, which does not support running of the locomotive, is successively provided with testing stand track wheels, cardan shafts, torque sensors, synchronous speed-up gear cases and test accompanying motors. The contact electrical network is arranged above the testing stand. One end of the locomotive is connected with the contact electrical network, and the other end of the locomotive is contacted with the testing stand track wheels through the locomotive wheel pairs. The testing stand is equipped with the flywheel apparatus. Flywheels are positioned behind the test accompanying motors and are connected with output ends of the test accompanying motors. When the locomotive is started, loading is acted onto the starting locomotive. The flywheel apparatus equivalent to moment of inertia is designed behind the test accompanying motors, that is to say, the linear motion inertia of the locomotive is equivalent to the moment of inertia of the flywheels, so that loading is acted onto the locomotive as long as the locomotive is started. Therefore, the flywheel apparatus helps to solve a problem about loading-free starting of the locomotive.
