| 摘 要： | The max collision force of ship-bridge collision is one of the most important references for bridge design. By means of nonlinear digital simulation method, the collision forces of the collisions between rigid bridge pier and ship bow were calculated out for four different ships, whose tonnages are 5 000, l0 000,50 000 and 60 000 DWT respectively. Curves of collision force-penetration and absorbed energy-penetration are obtained, and the data of the max loads are then summarized. On the basis of these curves and data, a set of curves describing the relationships between max collision forces and tonnages of the ships are successfully presented, by which the max collision forces of the ships-bridge with different tonnages and in different velocities can be estimated easily and reliably.

| Abstract: | The max collision force of ship-bridge collision is one of the most important references for bridge design. By means of nonlinear
digital simulation method, the collision forces of the collisions between rigid bridge pier and ship bow were calculated out
for four different ships, whose tonnages are 5 000, 10 000, 50 000 and 60 000 DWT respectively. Curves of collision force-penetration
and absorbed energy-penetration are obtained, and the data of the max loads are then summarized. On the basis of these curves
and data, a set of curves describing the relationships between max collision forces and tonnages of the ships are successfully
presented, by which the max collision forces of the ships-bridge with different tonnages and in different velocities can be
estimated easily and reliably. |
