Automatic design method for ship segmental hoisting scheme

Abstract

An automatic design method for a ship segmental hoisting scheme comprises the following steps: a selecting a segmental hoisting model; b selecting a hoisting equipment model; c segmentally carrying out characteristic position identification to generate an initial hoisting scheme; d carrying out interference judgment on a hoisting point position, process adaptation evaluation and rapid and dynamic adjustment; e selecting a hole plate with a corresponding type according to position characteristics of each hoisting point and a hoisting form, and pre-estimating a load and automatically selecting a suitable hole plate type; f carrying out rapid mechanical analysis on the hoisting scheme; and g generating a design drawing and finishing output. Being different from a conventional hoisting simulation system, the automatic design method for the ship segmental hoisting scheme, provided by the invention, is mainly used for a primary design period of the hoisting scheme; compared with the prior art, the design efficiency is higher and the reliability of the scheme is better; a software system developed by the method can realize the complete automation of the design work of the ship segmental hoisting scheme, and the disadvantages of a manual design of the hoisting scheme are completely overcome.

Description

technical field [0001] The invention relates to an automatic design method for a section hoisting scheme of a ship. Background technique [0002] Ship section hoisting refers to the operation that the construction unit uses lifting equipment to turn over or shift the hull sections. In order to ensure the smooth progress of the hoisting operation, most construction units have to carry out a strict hoisting scheme design before the operation. The design of hoisting scheme refers to the process of solving the feasible scheme of segmented hoisting within the constraints of given geometry, mechanics, and process rules. The scheme meets the requirements of stability and process applicability. Hoisting scheme design is a complex step-by-step optimization process. The feasibility and rationality of the scheme directly determine whether the hoisting work can be carried out safely and efficiently, thus affecting the entire ship construction cycle. [0003] At present, most domestic...

AI Technical Summary

Problems solved by technology

[0004] a. The design process is cumbersome and inefficient

[0005] ① The design of the lifting scheme requires a high technical level of personnel

[0006] ②Affected by the actual operation, the lifting plan needs to be revised several times

[0007] ③The workload of information calculation is heavy

[0009] Affected by subjective experience, it is difficult to optimize the coordination between multiple goals such as economy, safety, and ease of operation in artificially designed schemes. Too conservative design schemes will cause waste of materials. On the contrary, some people are too economical The scheme will have security risks

[0010] c. Experience-based design methods are not conducive to the establishment of scientific training systems
