摘要
利用LS-DYNA显式动力分析软件建立船舶撞击高桩码头的系统动力仿真模型,该模型将船舶—码头—土体视为整体系统,统筹考虑土体的弹塑性、桩与土体的流—固耦合效应和船体与橡胶护舷的面—面接触,可较好地模拟船舶撞击高桩码头过程中的大尺度和非线性变形。初步分析船舶载重量、船舶撞击方式和橡胶护舷等因素对最大船舶撞击力和撞击历时曲线的影响,为确定高桩码头的船舶撞击力提供了可行的动力学分析方法。
An explicit dynamic analysis software LS-DYNA is apphed to bulld a systemanc dynamic simulation model for the piled wharf being impacted by ship. The model integrates ship, wharf and soil into the system, plans as a whole the elastic plasticity of soil, fluid-structure interaction effect of pile and soil, and the interaction between ship and rubber fender. Therefore, the model can be applied to simulate large-scale deformation and nonlinear deformation well when the wharf is impacted by ship, A preliminary analysis is made for the influence on maximum impact force and impact duration curve by ship load capacity, ship impact way and rubber fender, which will provide a feasible dynamic analysis method for ascertaining the ship impact force of piled wharf.
