AbstractIn order to accelerate a heavy train model with a large dimension to a velocity higher than 500 km/hour for the moving model test, the compressed air is utilized to drive the model indirectly. The gas from an airgun impels a piston in the accelerating tube for a uniformly acceleration. The piston connects a driving device through a rope and the device promotes or pulls the train model for a desired velocity. The deceleration of the train model and the driving device are all realized by the friction between the brake plates and the rubber blocks. The principium experiment results reveal that the initial pressure of the airgun is linearly proportional to the kinetic energy of the model where the moving assembly with a weight more than 10 kg has been accelerated to 420 km/hour in an accelerating distance of 20m.
