The principle and classification of anti-collision blocks

There are many types of collision pads, which can be divided into two categories based on the principle of kinetic energy and the principle of conservation of momentum. The principle of kinetic energy is that a collision pad is a material or structure that can be destroyed or undergo plastic deformation and is placed in front of a collision object. It absorbs the kinetic energy of a moving vehicle by buffering or absorbing energy. This structure requires rigid support or obstruction to deform the absorbing material or structure and reduce the impact force on the vehicle. Another approach is to use the law of conservation of momentum to transfer the momentum of the out of control vehicle through some sand and water containers placed in front of the collision avoidance object, providing a buffering effect. This type of structure has strong construction mobility and is more convenient to apply.
