and S102, acquiring the total weight of the ship parts through the blanking layout of the whole ship. The total weight of the whole ship part comprises the total weight of the plate and the total weight of the section bar.
In this embodiment, the ship development program is used to directly extract the part information and the plate information in the blanking layout, and generate a corresponding data format, such as EXCELL data. The data of the whole ship parts in the blanking layout is the most accurate, so that the accuracy of data sources is ensured. Based on the above calculation formula of the material utilization rate, the total weight of the ship-wide part, which includes the total weight of the plate material and the total weight of the profile, needs to be obtained.
And step S104, acquiring the total weight of the actually used materials of the whole ship. The total weight of the used materials includes the total weight of the used plates and the total weight of the used section bars.

And S106, calculating to obtain the material utilization rate according to the total weight of the ship parts and the total weight of the actually used materials of the ship.
And dividing the total weight of the ship parts by the total weight of the actually used materials of the whole ship based on the calculation formula of the material utilization rate to obtain the material utilization rate of the ship.
According to the method for calculating the ship material utilization rate, provided by the embodiment of the invention, the total weight of ship parts and the total weight of actually used materials of a whole ship are obtained by utilizing the part information and the used plate information in the blanking layout, and the material utilization rate is calculated, so that the calculation accuracy can be improved.
Considering the requirement of the extended analysis, the total weight of each segment of the whole ship can be respectively obtained through the blanking layout, and the step of obtaining the total weight of the parts of the whole ship through the blanking layout of the whole ship can be executed according to the following steps:
(1) and extracting the total weight of the segmented plates and the total weight of the segmented sectional materials which are gathered by segments from the blanking layout. The whole ship can be divided into a plurality of sections, such as a double-layer bottom area, a bottom side cabin area, a transverse bulkhead area, a top side cabin area, a deck area, a head area, a cabin area, a tail area, a building area, a hatch coaming area, a bow, a bulwark, a rudder blade, a mast house and the like, and the total weight of the plates and the profiles is respectively gathered according to the sections to obtain the total weight. The total weight of the segments can be used for further analysis of the material usage of each segment, such as the utilization rate of the plate material of each segment, the utilization rate of a certain steel plate, the average thickness and the like.

And finally, taking the actually occupied weight as the weight of the folded combined plate.
(2) And summing the total weight of the used plates and the total weight of the used section bars after the reduction to obtain the total weight of the material actually used by the whole ship. The total weight of the material actually used by the whole ship, which is more suitable for the actual use condition, is obtained after the weight which is much added due to the fact that the plates are used for multiple ships is reduced.
