摘要
针对风力机-张力腿型支撑平台-筋腱耦合系统,对全耦合动力学仿真软件FAST的系泊载荷计算模块进行二次开发,采用时域分析方法对张力腿浮式风机(FOWT)WindStar TLP system筋腱失效模式下的瞬态响应进行数值仿真分析.重点研究50 a一遇海况中不同浪向下的浮式风力机支撑平台运动、机舱加速度和筋腱张力等关键参数的瞬态响应.结果表明:在该工况下支撑平台运动、机舱加速度、筋腱张力的瞬态响应较显著;失效筋腱位于背浪侧时的浮式风力机瞬态响应大于失效筋腱位于迎浪侧时的浮式风力机瞬态响应,当位于背浪侧的失效筋腱与波浪共线时,浮式风力机瞬态响应最大;在极端海况中筋腱失效模式下的筋腱系统安全系数符合美国船级社规范要求,表明该张力腿型浮式风力机具备较好的自存性.
The mooring load calculation module of the fully coupled dynamic simulation software FAST was recompiled,and the transient response of a tension-leg-platform floating offshore wind turbine(FOWT)named WindStar TLP system under tendon failure was numerically simulated using a time domain method,in terms of the coupled system of wind turbine,tension-leg-type support platform and tendons.The transient response of the key parameters,i.e.,platform motions,nacelle accelerations and tensions in the remaining tendons under different wave directions in 50-year extreme condition were investigated.Results show that the transient response of platform motions,nacelle accelerations and tendon tensions under tendon failure are significant.The transient response of FOWT with the broken tendon in back waves is greater than that with the broken tendon in head waves.And when the broken tendon in back waves is aligned with the wave,the transient response of FOWT is the maximum.The safety factor for tendon system under tendon failure in 50-year extreme condition meets the requirements of specification constituted by American Bureau of Shipping(ABS),which verifies the survivability of this tension-legtype FOWT.
