Study on load calculation of net clothes and applicability of hydrodynamic coefficient under screen model

In marine ranching, as an important part of marine ranching, the force of netting is extremely complex. The calculation of hydrodynamic load of netting is particularly important for the design and construction of marine ranching. In this paper, the theory of calculating the force of netting at home and abroad is sorted out, the MATLAB software is used to program, and the Screen calculation model is used to study the applicability of the Aarsnes formula used in the current Chinese ' Guidelines for the Inspection of Marine Fishery Facilities'. The applicability of the Aarsnes formula formula between PE material netting, metal netting and nylon netting and the influence of the presence or absence of nodules on the numerical calculation results of the netting are judged respectively, and the applicable conditions of the Aarsnes formula are summarized.
