A digital twin-based ship segment construction method

Abstract

The invention discloses a digital twin-based ship segmented construction method, which divides the ship segment into multiple construction nodes according to the ship construction sequence, and divides the digital twin map into multiple construction blocks corresponding to each construction node; in the digital twin The map establishes the mapping linkage relationship between multiple ship components in each construction block and ship components in two adjacent construction blocks; real-time monitoring of the construction data of ship components in each construction node, using the same construction block The influence coefficient of the ship component on the current construction plate is estimated by the mapping linkage relationship of multiple ship components in the ship component, and the influence coefficient of the ship component on the adjacent construction plate is estimated by using the mapping linkage relationship of the ship components in two adjacent construction plates; it is estimated that each The construction score of each construction plate and the overall score of the entire ship structure; the present invention predicts the influence of the segmented production data information on the segmental construction of the ship and the performance impact on the entire ship construction.

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
