| 中文摘要: |
| 目的 评估海上风电机组单桩基础和三脚架基础遭遇船舶撞击时的抗撞性能。方法 针对上述两种基础，采用LS-DYNA软件分析不同碰撞工况下的最大碰撞力、基础受损面积、机舱加速度最大值及基础钢材消耗量，获取两类基础的基础损伤程度和机组响应幅度。结果 单桩基础受损程度低于三脚架基础约22%，三脚架基础机舱响应值低于单桩基础约32%。结论 两类基础抗撞性能满足规范要求，未发生因基础失效引起的倒塔事故，机头不存在脱落风险，单桩基础在基础损伤方面表现更好，而三脚架基础在机组机舱响应方面表现更好。 |
| 英文摘要: |
| This study is devoted to evaluate the anti-impact performance of offshore wind turbines (OWTs)’ monopole and tripod foundations subject to ship impacts. Contraposing to the above two foundations, software LS-DYNA was adopted to analyze the maximum collision-force, the damage area, the maximum nacelle acceleration and the steel consumption under different impact conditions to obtain the foundation damage and the OWT response of the two types of foundations. The results showed that the damage of monopole foundation was about 22% lower than that of tripod foundation; the nacelle response of tripod foundation was about 32% lower than that of monopile foundation. It is concluded that there is no risk of tower collapse accident caused by foundation failure and no risk of nacelle falling off for two types of foundations meeting the anti-collision performance requirements of the specification. Meanwhile, the damage of monopile is lighter than that of tripod, the nacelle response of tripod is better than that of monopile. |
