There is an emergency break device for the moving vehicle which is composed
of the following equipments:
(1) Long slender cylinders filled with water on both sides of towing tank along rails.
(2) Bullet shape piston inside the cylinder.
(3) Fook and cable for connecting with moving vehicle with 50(tons) of weight.
Drug force of water inside the cylinder decelerates the moving vehicle, when needed.
In this case, breaking performance is analyzed using fluid-structure interaction
technique.
