主 题：moving train model acceleration deceleration magnetic braking air gun compressed air
摘 要：In order to accelerate a heavy train model with great dimensions to a speed higher than 300 km h?1 in a moving train model testing system,compressed air is utilized to drive the train model *** gas from an air gun pushes the piston in an accelerating tube *** piston is connected to the trailer through a rope,and the trailer pulls the train model to the desired *** the testing section,the train model enters the deceleration *** speed of the train model gradually decreases because of the braking force of the magnetic braking device on the bottom of the train model and the steel plates fixed on the floor of this *** dissipation of kinetic energy of the trailer is also based on a similar *** feasibility of these methods has been examined in a 180 m-long moving train model testing *** speed of the trailer alone reaches up to 490 km ***,a 34.8 kg model accelerates up to 350 km h?1;the smooth and safe stopping of the model is also possible.
