Ship block construction method based on digital twinning

Abstract

The invention discloses a ship block construction method based on digital twinning, which comprises the following steps: dividing a ship block into a plurality of construction nodes according to a ship construction sequence, and dividing a digital twinning map into a plurality of construction plates corresponding to each construction node; establishing a plurality of ship components in each construction plate and a mapping linkage relationship between the ship components in two adjacent construction plates in the digital twin map; monitoring building data of the ship assemblies in each building node in real time, and estimating the influence coefficient of the ship assemblies on the current building plate according to the mapping linkage relation of the multiple ship assemblies in the same building plate; budgeting influence coefficients of the ship components on the adjacent building plates by utilizing a mapping linkage relation of the ship components in the two adjacent building plates; and predicting the construction score of each construction plate and the overall score of the whole ship structure. According to the method, the influence of data information of segmented production on ship segmented construction and the influence on the performance of the whole ship construction are pre-judged.

Description

technical field [0001] The invention relates to the technical field of digital twins, in particular to a method for building sections of ships based on digital twins. Background technique [0002] Shipbuilding involves many types of work, complex processes, long cycle times, capital and labor-intensive, and large engineering workloads. It is a typical discrete manufacturing. The shipyard needs to have complete supporting infrastructure and professional equipment, a large number of skilled workers and managers of various types of work, complete suppliers, a good port environment, and sufficient funds to successfully complete the shipbuilding task. At present, the backwardness of shipyard manufacturing technology, mode and level is also one of the bottlenecks restricting the development of shipbuilding industry. The digital level of the traditional shipbuilding method is insufficient. Shipbuilding is a labor-intensive industry. The work in the construction stage of the dock ...

Problems solved by technology

[0005] (1) Lack of comprehensive perception capabilities. At present, the data of employees in the shipbuilding process is in the form of isolated islands, and there is no data integration. It is impossible to obtain the geometric attributes, physical attributes, actions, energy consumption, etc. of the entire ship when a ship is operating in sections. Data, so that the digital twin lacks sufficient effective data during simulation;

[0006] (2) Difficult to catch faults

The occurrence of faults is often the result of a combination of multiple factors, and the correlation between them is very complicated. At the same time, the damage caused by the faults will also bring obstacles to the later accident investigation.

It is difficult to find the fault formation mechanism by using historical data and real-time data
