Twin-truss system design for antarctic krill trawl processing ship
摘要
Abstract
Aiming to improve the fishing efficiency of antarctic krill processing ships by averting the potential crushing of krill in the trawl to meet quality requirements, a twin-truss system design is proposed which has higher efficiency compared with the traditional system installed in ships. To simulate this design, an analysis of forces acting on the twin-truss structure is conducted under tethered and operating conditions using the structure model method, and an appropriate distance between trawl winch and truss structure, as well as the range for limiting the distance of the horizontal locating cable and truss structure, are obtained. It can also prevent the truss structure from breaking down, enabling the efficiency of trawling and horizontal locating cables during fishing operations. The simulation shows that the new twin-truss system design can improve the efficiency of trawl processing ships, whilst maintain the safety of the truss structure. This design can provide an optimal solution for the truss systems of national antarctic krill processing ships.关键词
