基于Orcaflex的张力腿网箱水动力分析

基于凝集质量法和等效网目法对网衣进行等效处理,利用大型水动力分析软件Orcaflex建立张力腿网箱模型,求解分析张力腿网箱在在波浪作用、海流作用和波-流联合作用3种外载荷情况下浮于水面和下沉时系泊缆有效张力的变化情况。分析结果可作为张力腿网箱安全建设的理论依据,对张力腿网箱模型在海洋工程中的应用具有一定的参考价值。

Hydrodynamic analysis of tension leg cage based on Orcaflex

Based on the lumped mass method and the equivalent mesh method, the net garment is equivalently treated. The tension legged cages model is established by the Orcaflex large-scale hydrodynamic analysis software to solve the three types of external loads such as wave action, ocean current action and wave and flow joint action in the case of tension leg cages floating in the water surface and sinking two kinds of conditions of the cage mooring cable effective tension changes. The results of the analysis can be used as the theoretical basis for the safety construction of tension legged cages and have certain reference value for the application of tension legged cages model in marine engineering.
