Abstract

The invention discloses a dynamic compensation method for ship segmental construction curved surface deformation. The dynamic compensation method comprises the following steps: fitting a curved surface construction segmental deformation compensation model based on an acquired actual ship segmental condition to obtain a theoretical height of a jig frame; establishing an association relationship between the jig frames based on the segmented deformation range and the compressive load of the ship; and carrying out segmented deformation compensation according to the actual height and the theoretical height of the jig frames by adopting a preset jig frame height self-adaptive regulation and control algorithm. According to the ship segmental construction curved surface deformation compensation method, the association relationship between a reference jig frame and subordinate jig frames of all levels is constructed, so that other subordinate jig frames can be automatically adjusted according to the change of the standard jig frame during compensation, the problems of low manual repairing efficiency and poor repairing precision are solved, whether the jig frame type value conforms to the sectional type value or not does not need to be manually checked, and the deformation compensation precision and efficiency and the sectional construction quality are improved.

Description

technical field [0001] The invention relates to ship building, in particular to a method for dynamically compensating deformation of a ship's segmented construction surface. Background technique [0002] The tire frame used for ship block construction has developed from the early formwork type, pillar type, and fulcrum type to the current CNC tire frame, flexible tire frame and intelligent tire frame, and its functionality has gradually improved, but the above-mentioned various tire frames are all individual , There is no mutual connection between the tire frames. In the process of ship segmental construction, each tire frame needs to be adjusted and controlled sequentially, which cannot maintain the segmental shape well, and the compensation of the tire frame for segmental deformation has subjective will, and the accuracy of compensation variables is poor. [0003] The Chinese invention patent application with the publication number CN109050789A and the publication date of...
