Problems solved by technology

[0005] In view of this, the present invention provides a train motion simulation system to solve the problem that the model used in the existing simulation system is simple, only from the traction force of the train motor and the frictional braking force of the skid, and not from the internal factors of the train. Considering the motion characteristics of trains from different angles, it cannot meet the requirements of engineering applications
