Catamaran as a new type of ship, its advantage is obvious. Catamaran deck area available is large, and has good stability and floating resistance. Arrangements for personnel and equipment is very convenient. Enough of the deck area is reserved providing all kinds of mechanical equipment with very large space. Therefore, this paper adopts the catamaran hull as kelp cutter.In this paper, according to current situation of Rongcheng. kelp breeding design of kelp harvest ship is studied. This paper first introduces the features of seaweed harvesting. Due to the need to use catamaran hull, connection bridge position is different from general catamaran. So there is no instance to refer to.Using kelp harvest ship direct calculation of structural strength is adopted, and its optimization design of supporting beams is done. For the hydraulic system, with the use of AMESim simulation calculation is carried out.In this paper, the main work content is as follows:1、In view of the special catamaran which is not direct calculation formula is derived for the connection bridge, and introduces the calculation catamaran several calculation methods of lateral bending and torsion condition,compared to the chosen Scott method.2、This paper briefly introduces the kelp ship part of the harvest as well as the structure and function of each part.This paper expounds the working principle of seaweed harvesting boat.3、Using finite element analysis software for kelp harvest ship hull structural strength calculation, with Scott method calculate the working condition of horizontal bending and torsion load conditions, according to the nature of the load to select a reasonable form of constraints. The whole ship in transverse bending and torsional stress distribution condition, analyse the stress distribution law of connection bridge area.Optimize separately,for key components support beam with its produce displacement as constraint conditions, and then calculate and check according to the results of the optimization model for finite element.The optimized plan completely satisfies the displacement constraint conditions.4、Using the AMESim simulation analysis software of hydraulic system, hydraulic system of HCD simulation and physics simulation experiment, the effective verify the factors that influence the hydraulic cylinder and hydraulic motor sports will speed.Flow changes impact on the hydraulic cylinder pressure and hydraulic pressure motor speed quantify are characteristic curve, the simulation experiment for the hydraulic system design whether meet the condition of effective verification.
