| 摘 要： | 采用有限元方法，分析了桩柱式结构模态，得到结构振型变化，且研究了桩柱式平台结构的波浪力载荷作用机理，得到平台结构在时域中桩柱结构所受波浪力变化情况.同时分析了不同桩柱形式结构纵荡、横荡和垂荡以及横摇、纵摇和首摇方向波浪力变化.结果表明:多桩柱平台结构频率变化范围集中、振型变化较小；横荡方向波浪作用力小，纵摇方向波浪作用力大.

| Abstract: | Based on the finite element method,the wave force mechanism on a platform structure of offshore wind turbine was analysed and the dynamic response and wave force variation on the platform structures were obtained in time domain.The wave force variations on platforms with different pile structure types in the directions of surge,sway and heave as well as of roll,pitch and yaw were investigated.The results show that for multi-pile structure platforms,the frequency changes only in an arrow band and the vibration mode has only a little change;in sway direction the wave force is minimum and in pitch direction the wave force is maximum. |
