Analysis of Steel-Aluminum Anti-Collision Device for Pier Protection

Ship-bridge collision accidents often jeopardize the bridge structure, shorten the service lifespan, decrease the safety and durability of the bridge and cause losses in the seismic capacity. Therefore, it is necessary to conduct research and simulation on anti-collision facilities for piers. Aluminum foam has significant advantages in anti-collision and energy absorption performance as a new type of foam material. This paper uses ANSYS/LS-DYNA to simulate the process of a ship-bridge collision and analyzes the energy absorption effects of the steel-aluminum anti-collision sandwich structure.
