A method for setting out the hull shape of a stern post asymmetrical ship

Abstract

The invention provides a method for setting out the hull shape line of a stern column asymmetrical ship. The shape line is smoothed through the left and right sides of the stern respectively, which ensures that the asymmetric hull shape line of the stern column can be set out through the ship design software, and at the same time according to Define the boundary lines of different regions on the starboard and starboard sides to ensure that the work on the starboard side of the stern and half ship can be carried out on the basis of the already staked port side model line. Only by adjusting the model lines in different areas can the stern and half ship’s starboard model line be obtained , to avoid the repeated work of the same area on the left and right sides, and to avoid the inconsistency of the molded lines after stakeout in the same area on the left and right sides during the smoothing process.

Description

technical field [0001] The invention relates to the technical field of lofting and smoothing of ship hull lines, in particular to a method for setting out hull lines of ships with asymmetrical stern posts. Background technique [0002] The hull shape line is the theoretical hull curve obtained by the upstream design institute based on the experimental design of the mother ship and the ship model pool. The shape line obtained at this stage is only for the purpose of meeting the needs of the overall performance calculation, so there will be local uneven areas , if the hull is built according to this type of line, it will cause the hull plate to be uneven and unsightly, and it will lead to an increase in the navigation resistance of the underwater part. Therefore, before the shipyard designs and builds a ship, the first step is to perform three-way smoothing on the hull shape line provided by the design institute, and obtain the smooth shape line diagram and shape line data, wh...

Problems solved by technology

At present, a new type of energy-saving and environment-friendly ship type, the stern area is subverting the traditional asymmetric form of port and starboard, but the hull shape of this form cannot be staked out through the existing ship design software, such as abandoning the stakeout software through the original manual stakeout , although the lofting work can be completed, the workload is multiplied and the smoothing accuracy is far less than that of software lofting accuracy. What is more critical is that manual lofting cannot generate profile data for subsequent design and modeling
