Global dynamic virtual reality carrying method based on precision database

Abstract

The invention discloses a global dynamic virtual reality carrying method based on a precision database. The method includes the steps that according to the number of blocks, and after precision measured data and precision theory data of one block are compared according to a sequence, the data are stored in a precision intermediate state database; outside environments are introduced for virtual reality simulation carrying of precision influence analysis and block carrying and hoisting plans, and obtained simulated results are stored in the precision intermediate state database; two blocks subjected to simulation twice are adjacent blocks, two simulation results serve as intermediate states and then simulation carrying is carried out again, and accordingly carrying precision states of the two blocks are obtained; the steps are repeated till virtual reality carrying of all the blocks of a whole spaceship is completed. The method enables main size precision of the whole spaceship to be controllable, and virtual reality carrying efficiency of the blocks of the whole spaceship is improved.

Description

technical field [0001] The invention relates to a global dynamic simulation loading method for a ship hull. Background technique [0002] After the rapid development in recent years, the overall scientific and technological level of my country's shipbuilding industry has made significant progress. The technical performance and construction quality of some large ships have reached or approached the world's advanced level. However, in the field of most large ships, my country has not yet formed an independent development capability. Shipbuilding is different from machinery manufacturing. It has many processes and manufacturing links, large workpieces, and high difficulty in quality control. In particular, there are many factors affecting the accuracy of components, and the control and management are complicated. The steel is pre-treated, parts processed, parts assembled, sub-assembled, and docked to form a hull. During this process, various types of processing are required, ...
