[0040] Step S2: According to the installation method of the equipment, the base structure can be divided into a stand-up type, a wall-mounted type, a wall-mounted type, an inverted type, a stand-up type, a backrest type, etc.; according to the base structure, the base structure is supplemented on the basis of the universal base template to complete the creation of a virtual universal base model, and the completed virtual universal base model is placed in the base model library for easy call; according to the installation method of the equipment; the completed virtual universal base model is placed in the Catalog Browser base template library for easy call, such as Figure 6 shown.

[0041] Step S3: read the installation interface and weight information of the device, call the virtual universal base model, and generate a device virtual base model under the structure tree of the device model; the device model and the device virtual base model are associated, and the device virtual base model is automatically arranged with the arrangement of the device model, such as Figure 7 shown.

[0042] Step S4: Arrange the equipment virtual base model and equipment model on the entire hull structure; in step S4, the equipment virtual base model participates in collaborative design as the layout background of the hull, and can timely discover the interference between the equipment virtual base model and the piping and cables; the arrow direction of the model of the structure attachment surface must be consistent with the arrow direction of the virtual universal base model. Figure 8 As shown in the figure, after the equipment is arranged according to the preliminary design input, the virtual base is arranged on the hull structure together with the equipment. At this time, the virtual base can be used as a layout background to participate in collaborative design, which is convenient for designers to promptly discover the interference between the base and the piping system, cables, etc.

[0043] Step S5: The equipment virtual base model identifies the hull structure boundary according to the final layout position of the equipment model, matches the corresponding plate thickness and material, and automatically converts the equipment virtual base model into a physical base model. After the equipment technical status is determined, the virtual base model identifies the hull structure boundary according to the final layout position of the equipment, matches the corresponding plate thickness and material, such as Fig. 9 and 10 shown.

[0044] The present application provides a method for modeling a ship equipment foundation, which can realize the rapid generation of an equipment foundation model and ensure the consistency of the technical status of the foundation after multiple deployments of equipment of the same specification throughout the ship.
