The structure of the cushion Kinetic energy principle
anti-collision pad is generally composed of the end, energy
absorbing material, both sides of the beam, diaphragm and back
support. After a vehicle collides with the anti-collision pad, it
absorbs the energy of the colliding vehicle through the deformation
of the end part and energy absorbing material, and the back support
is used to resist the impact force of the vehicle.
Energy absorbing material is generally foam material or rubber
material, the principle of the anti-collision pad for the front and
side of the vehicle has a good effect of energy absorption and
guidance, and the system after the collision, the main components
can be reused, convenient and fast maintenance and low cost, the
disadvantage is a little more complex and high cost of the initial
installation.
The principle of momentum conservation is generally composed of
sand filling or water filling anti-collision cylinders (piers) of
different masses arranged in a certain order. After a vehicle
colliding with the anti-collision cushion, the momentum of the
vehicle is transferred to the anti-collision cylinder in turn,
which reduces the speed of the vehicle and the anti-collision
cylinder in turn, and finally makes the speed of the vehicle lower
than 15km/h.
