Description

technical field [0001] The invention relates to computer-aided process design technology, in particular to a hull segment assembly sequence planning system and a planning method thereof. Background technique [0002] Shipbuilding is a complex manufacturing project, which is assembled and welded by thousands of components. It has the characteristics of wide range of operations, heavy workload, various types of work, complex structure, cumbersome installation, and high labor costs. Most of the assembly work in the hull is completed by construction personnel, and the operating experience of on-site workers will largely affect the final assembly quality. At present, the main construction method of large and medium-sized ships is the segmented construction method, that is, in the design stage, the entire hull structure is divided into segments of different sizes according to certain principles; Folding is carried out on the slipway or dock to assemble a complete hull. Therefore...

Problems solved by technology

[0004] Due to the complexity of the hull segment construction process and the many influencing factors, the segment assembly process planning is difficult, the formulation cycle is long, and the process of process evaluation is complicated. At present, the assembly process of large shipyards in my country is mostly based on According to existing work experience, there are three main problems in this method: on the one hand, the formulation process of the process planning process is too dependent on empirical judgment, the degree of intelligence is low, and the corresponding standard document guidance is lacking, which makes the process of assembly process formulation slow and difficult. There are also great hidden dangers in quality stability; on the other hand, there is a lack of corresponding sorting and inheritance of existing assembly process knowledge, which leads to repeated process formulation and greatly prolongs the entire production cycle; in addition, there is a lack of corresponding evaluation of the established assembly process And the verification system makes it difficult to evaluate the pros and cons of the assembly process, which also brings many problems to the actual production process
