摘    要:对养殖网箱在海流作用下变形而导致的网箱养殖空间减少的有效把握,是网箱设计计算的核心课题之一。本文提出1种基于有限元原理的用于预测养殖网箱耐流特性的数值模拟方法,以期依据计算机模拟结果,在一定程度上代替传统的模型试验和海上实际测试,寻找提高网箱耐流特性的技术措施和解决方案。

关 键 词:有限元  养殖网箱  耐流特性  数值计算

Abstract:It is one of the key projects in fish cage design and calculation to predict the change of cage shape resulting from currents,since low anti-current characteristics of the cage brings some severe effects on fish farming.In this paper,a nonlinear finite element method(FEM) is employed to determine the anti-current characteristics of the cage by solving the equilibrium configuration and tension of the cage.It is expected that some measures or methods to improve the anti-current characteristics of the cage can be found by numerical simulation instead of the model test in the flume tank and the field trial on the sea.
Keywords:FEM  fish cage  anti-current characteristics  numerical calculation
