Problems solved by technology

[0004]The planned welding man-hours obtained according to the above model are not accurate enough, and cannot fully reflect the specific impact of the actual construction method of each segment on the welding man-hours
Due to the limitations of the stages of ship section design and construction and the division of labor, it is difficult to completely and accurately define the construction method information contained in the ship section design software system, and the welding posture information obtained according to the above mode cannot reflect the real welding. attitude

Embodiment

[0028] Example: such as Figure 1-7 As shown, the present invention provides a method for calculating welding man-hours based on ship block construction, characterized in that the management method includes the following steps:

[0029] S1: Extract the 3D geometric model, assembly structure hierarchy information and weld seam information by the ship design software; extract the part geometric model and attribute information in units of segments; obtain the complete 3D geometric model of the part through model reconstruction and model Boolean operations, The 3D geometric information of each part can be accessed independently. Multiple parts are combined into small groups, medium groups or segments, and the reconstructed geometric model of a segment A11C is as follows figure 2 As shown; the COM interface component is used to extract segmental assembly level information. The assembly level information includes parts, subgroups, middle groups, and segmental assembly relationship...

Abstract

The invention discloses a welding man-hour calculation method based on a ship block construction mode, comprising the following steps: extracting three-dimensional geometric model, assembly structurehierarchy information and weld seam information from ship design software; According to the construction process specifications and requirements, At that visual interface of the three-dimensional geometric model, input the construction mode of group erection, middle erection and section, obtain the construction datum level information, calculate the angle information of the weld seam under the construction state, determine the welding posture of the weld seam, determine the correction coefficient of the welding man-hour, and determine the preparation time before welding and the post-welding treatment time; It is helpful to improve the accuracy and convenience of calculation of weld planning man-hour, change the influence coefficient from discrete skip type to continuous one, improve the accuracy of calculation of weld planning man-hour is also helpful to reduce the cost of welding man-hour, and help to scientifically and reasonably determine the construction mode of segments.

Description

technical field [0001] The invention relates to a management method, in particular to a method for calculating welding man-hours based on a ship segmented construction method, and belongs to the technical field of data management. Background technique [0002] Welding work is the core type of work in shipbuilding and ocean engineering enterprises. Welding man-hours have a decisive impact on ship construction costs and construction cycles. It is of great significance to improve the accuracy and convenience of welding planned man-hour calculations. [0003] The current calculation model of ship segmental welding man-hours generally considers information such as weld length, groove, plate thickness, welding posture, etc., and combines the rated welding man-hours of the enterprise, and then appropriately increases or decreases to obtain the planned welding man-hours. The welding posture generally includes different position postures such as flat welding, vertical welding, horizo...
