Description

TECHNICAL FIELD

[0001] The present application relates to the field of train experiment simulation, in particular to a train collision simulation model device and a display system thereof. BACKGROUND

[0002] In the process of researching high-speed trains, in order to more intuitively understand the process of train running, and to facilitate clear display, a model designed to be reduced in proportion is usually used for simulation demonstration.

[0003] In the prior art, a simulation train and a guide rail are used in combination to realize simulation display of meeting and collision, and an ejection device and a traction assembly are used to drive the train model to accelerate movement.

[0004] However, in the actual simulation process, since the train model truly simulates the running speed of the train, it has a large impact force, and in the process of collision experiment simulation, a large inertial impact is caused, which is extremely easy to cause deformation of the train or even cause the train to fall off the guide rail. However, the common solution in the prior art is to set the guide rail to be T-shaped, thereby preventing the train model from falling off, but under the high-intensity inertial impact, friction between the lower wheels of the train and the guide rail is caused, thereby causing the lower wheels to deform and fall off under the inertial impact.
