Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] Attached below figure 1 And examples, further describe the workflow of the rapid design method of the schematic diagram of the ship system based on CAD and PDM.

[0033] Step 1. The administrator creates a new ship model product Product1 in the PDM interface data submission system;

[0034] Step 2, the administrator creates a system structure tree in the system browser of the PDM interface data submission system according to the system composition of the product Product1 (including the affiliation relationship between each subsystem and the responsible department of each subsystem);

[0035] Step 3. The administrator creates an area structure tree in the area browser of the PDM interface data submission system according to the cabin composition of Product1 (including the affiliation of watertight areas, decks, and cabins);

[0036] Step 4. Accordi...

Abstract

The invention discloses a fast design method of a ship system schematic diagram based on CAD and PDM. According to the method, a management model based on design data is established in PDM, and an architecture including the information of a system structure tree, a regional structure tree, components, devices, interfaces and the like is created; an interface integrated with the PDM is developed in the AutoCAD, which enables designers to realize the automatic numbering of equipment, the automatic generating of annotations and specification lists, the automatic identification of equipment compartment information, the one-key extraction of equipment weight and gravity, the one-key modification of equipment symbols and the version management and online revision of design data after a system design in the schematic diagram is completed. The method can effectively improve the work efficiency of designers and the management level of design data, and is applied to various majors in the field of ship overall design.

Description

technical field [0001] The invention belongs to the field of ship digital design, and relates to a rapid design method of a ship system schematic diagram based on CAD and PDM. Background technique [0002] The overall design of a ship is a system engineering involving a wide range of specialties, complex subsystems, and numerous equipment. There are many performance indicators and equipment information of the ship. Compile a large number of schematic diagrams, count various design data and compile relevant technical documents. [0003] At present, the PDM system used in the overall design of the ship is based on document management for the schematic diagrams submitted by various professional departments. The design data in the CAD drawings has no correlation with the equipment and related design parameters in the PDM system, and the various information generated from the schematic diagrams There is also a lack of automatic association between class documents and various des...
