An Anti-Collision Device with Circumferentially Energy Absorption under a Local Impact

A new design of anti-collision device is present in this paper. When the collision occurs, with the deformation movement, the anti-collision device can transfer the collision energy to the non-contact area, store the energy and release after collision, which can not only protect the protected object, but also reduce the damage to the collision-causing object, ensuring the anti-collision device itself can be reusable. As a result, this design of anti-collision device can greatly reduce damages and economic losses caused by the accidental collision.
