The Study of Slamming Pressure in the Tail of Bow Carrier

摘要


Due to transportation characteristics, bulk carriers have a relatively flat structure, and the wave slamming during navigation is larger than that of ordinary ships. Therefore, reasonable forecasting of slamming loads is of great significance to the structural design of ships. The calculation and prediction of ship slamming pressure need to fully consider the three-dimensional characteristics of the ship and include the impact of the hull movement on the sniper operation. At the same time, the selection of a reasonable slamming coefficient is also a crucial factor. This paper takes a bulk carrier as an example, analyzes the ship's motion response in waves using wave-tolerance theory, and discusses a reasonable dimensionless attack coefficient to forecast slamming loads. The slamming load is mapped to the finite element calculation model of the bulk carrier and the response results of each component under the slamming pressure are obtained. Compared with the allowable stress of the structural material, the slamming strength evaluation of the bulk carrier is realized.
