外载荷作用下拦阻网的受力分析

深海养殖场中时常会遇到外来物体的冲撞,如船只、漂浮物或鲨鱼等,现通常会在渔场外围设置拦阻网,以保护渔场设施和养殖鱼类。针对船舶误闯入渔场区,撞击在拦阻网衡量上,文章基于显式动力学的分析理论并使用ANSYS/LS-DYNA程序,通过建立拦阻网简化模型、划分网格、计算分析等,对拦阻网结构受力及整体响应进行分析,并校验拦阻网绳强度,给拦阻网具体设计提供一定的理论基础。

Stress Analysis of Blocking Net under External Load

Deep-sea farms often encounter collisions with foreign objects, such as boats, floats or sharks. A barrier network is usually installed outside the fishery to protect fishery facilities and farm fish. In view of the ship accidentally entering the fishery area, the impact is measured in the intercepting net. The article is based on the analytical theory of explicit dynamics and uses the ANSYS/LS-DYNA program. The domain is simplified by model building, meshing, parameter setting, and calculation. Analysis, etc., analyzes the force and overall response of the blocking network structure, and tests the strength of the network rope to provide a certain theoretical basis for the specific design of the blocking network.
