摘　　要：为防止深海养殖场遭到船舶、漂浮物和鲨鱼等外来物体的冲撞,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。针对船舶误闯渔场区撞击拦阻网横梁或网绳的情况,基于显式动力学分析理论并采用ANSYS/LS-DYNA程序,通过建立拦阻网简化模型、划分网格和计算分析等,对拦阻网支撑梁结构和拦阻网绳强度进行评估,为拦阻网具体设计提供一定的理论基础。In order to avoid the collisions from external objects such as boats,floats and sharks,deep-sea farms usually set blocking nets around the fishery to protect the fishery facilities and fish.Aiming at ships entering the fishing area by accident and hitting the barrier net beams or ropes,the article is based on the explicit dynamic analysis theory and uses ANSYS/LS-DYNA program to simplify the model,divide the grid and calculate and analyze the barrier net to evaluate the structure of the barrier net support beam and the strength of the barrier net rope,which provides a certain theoretical basis for the design of the barrier net.
