讨论了近海结构物上的流体载荷,着重涡旋脱落的产生及效应。进行了有涡旋脱落时的疲劳分析。利用最新的推广Mincr法则来计算累积损伤,从而估计了近海结构物的疲劳寿命。
The fluid loads on offshore structures are discussed, focusing on the generation and effects of vortex shedding. Fatigue analysis with vortex shedding was performed. Cumulative damage is calculated using the latest Mincr generalization to estimate the fatigue life of offshore structures.
