Embodiment 1
[0051] Embodiment 1: A dynamic control method for train simulation driving.
[0052] In the train driver training system, when the full-featured train simulator is used to train trainees' driving skills, the fidelity of the simulated driving dynamics directly determines the quality level of the simulator: first, the full-featured train simulator must accurately simulate In the process of train traction or braking under real running conditions, the force relationship of the whole train corresponding to the driver's traction or braking operation and the longitudinal traction or braking acceleration information, the calculation accuracy of traction calculation and train dynamics will directly determine the accuracy of the simulator. Fidelity; Secondly, due to the limited dynamic range of the 6-DOF motion platform, it is impossible to directly simulate the continuous acceleration of the cab in the longitudinal direction, resulting in relatively low fidelity. The longitudinal direc...

[0071] Embodiment 3: In order to verify the driving dynamics control method of the train dynamics simulation simulator proposed by the present invention, a full-featured driving simulation simulator for a model high-speed EMU was tested in a domestic train driving training base. Full-featured train driving simulation simulator driving test effect, such as Figure 4 shown. Figure 4 A records the traction brake handle operation record during this simulated driving process; Figure 4 b records the speed curve of the train during the simulated driving process; Figure 4 c records the train longitudinal acceleration curve (solid line) obtained by the traction braking level through the train traction calculation module and the train dynamics calculation module during this simulated driving process, and the simulated driving dynamics converted longitudinal acceleration curve (dotted line), Through comparison, it is found that the longitudinal acceleration curves in the two cases b...
