Anti-Collision Customized Color Highway Safety Equipment Crash Cushion

Crash pad is another name for the name of anti-collision block, cushion pad, rubber block, etc. The anti-collision pad is mainly installed on the edge of the loading and unloading platform, which facilitates the truck to park and reduces the difficulty of the driver to park, and plays a role in protecting the cargo platform, the cargo platform loading and unloading equipment and the truck from damage. Anti-collision adhesive is one of the necessary protective facilities for unloading platform. Material and process The anti-collision adhesive made of rubber material is usually applied to the entire front edge of the cargo platform, while the anti-collision adhesive made of natural rubber (the same material as the automobile tire) is usually used to fix the loading and unloading equipment on both sides.

The principle and classification of crash pads:
There are many types of crash pads, which can be divided into two categories: kinetic energy principle and momentum conservation principle according to the anti-collision principle. The collision pad is a material or structure that can be destroyed or produce plastic deformation in front of the collision object, and absorbs the kinetic energy of the driving vehicle by buffering or absorbing energy. This structure requires rigid support or block, so that the energy-absorbing material or structure deforms to reduce the impact force on the vehicle. The other is according to the law of conservation of momentum, through a number of sand and water containers set in front of the anti-collision object to transfer the momentum of the out-of-control vehicle, play a buffer structure. This kind of structure has strong construction mobility and convenient application.

The structure of the crash pad:
Kinetic energy principle Collision pads are generally composed of end heads, energy absorbing materials, both sides of the beam, cross partition and back support. After vehicle collision pads, the energy of the collision vehicle is absorbed through the deformation of the end part and the energy absorbing material, and the back support is used to resist the momentum of the vehicle. The energy absorbing material is generally foam material or rubber material, this principle of the collision pad for the front and side impact of the vehicle have a good energy absorption effect and guidance, and the system after the collision, the main components can be reused, easy and fast maintenance and low cost, the disadvantage is that the initial installation is slightly complicated and high cost.
The principle of conservation of momentum is generally composed of different masses of sand-filled or water-loaded bumpers (piers) arranged in a certain order, after the vehicle crashes into the bumpers, the momentum of the vehicle is successively transmitted to the bumpers, so that the speed of the vehicle and the bumpers is successively reduced, and finally the speed of the vehicle is reduced to below 15km/h.

The design of crash pads:
The following factors should be considered in the design of the collision pad:
(1) Because the anti-collision pad is exposed to the external environment, its material should meet the requirements of high and low temperature resistance and corrosion resistance.
(2) The collision pad should be designed so that no debris flies out in the collision, and after the frontal and side crash tests, the debris generated by the collision pad should be retained in the collision pad, and can not cause injury to the collision vehicle, surrounding pedestrians and other vehicles.
(3) After the vehicle hits the crash pad, the driver's acceleration is less than 12g, and the average acceleration of the last 10ms is less than 20g, and after the out-of-control vehicle hits the crash pad, the vehicle cannot cross the crash pad; Also can not bounce, into the adjacent driving lane, so as not to collide with the car behind, a secondary accident.
(4) The height of the collision pad is not too high or too low; Too high easy to block the driver's line of sight; Too short, the vehicle is easy to climb on the crash mat. In the design of the collision pad, for economic considerations, after the collision between the out-of-control vehicle and the collision pad, the vehicle generally will not stop, so a certain safety buffer distance should be set between the collision pad and the protected obstacles, generally about 60cm. When the collision pad of the momentum conservation principle type is used in the combination of collision cylinders, the number of required cylinders can be determined by trial calculation after the arrangement is determined. Because the collision process is more complex, experimental or empirical values and layout sequence are generally used, and no less than 5 collision cylinders are generally combined.
