Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a method, apparatus, equipment, and computer-readable storage medium for outfitting a ship's compartment. Background Technology

[0002] Currently, the outfitting process for ship compartments involves first measuring and modeling the ship's compartments on shore, then prefabricating decorative panels based on the modeling results, and finally installing the panels while the ship is on the water. However, this method has the following technical problems: A ship is not a rigid body, but rather a massive thin-walled box girder. When a ship transitions from dry dock to a floating state, the uneven distribution of gravity and buoyancy along its length causes the hull beams to bend longitudinally. Furthermore, static measurements taken on shore only represent the ship's geometric state under specific support conditions, not its true state during long-term service at sea. Therefore, decorative panels prefabricated based on shore measurements are highly susceptible to problems such as interference, compression, bulging, or excessive gaps during installation on water, leading to installation failure. Summary of the Invention

[0003] This application provides a method, apparatus, device, and computer-readable storage medium for outfitting a ship's compartment.

[0004] In a first aspect, embodiments of this application provide a method for outfitting a ship's compartment, comprising: Based on the environmental point cloud data of the ship's cabins in the water state, the rigid body motion data of the hull, and the elastic strain data of the bulkheads, the static geometric model of the ship's cabins in the water state is reconstructed after they are subjected to only gravity and buoyancy. Based on the static geometric model and the preset ship vibration mode diagram, the bulkhead surface is segmented to generate multiple decorative panel geometric models and the corresponding installation points for each decorative panel geometric model; Based on the vibration spectrum of the mounting point in the static geometric model, generate the connector model corresponding to the mounting point; Based on the geometric model of the decorative panel, the mounting point, and the connector model, the outfitting design result is generated, and the outfitting design result is associated with and stored with the bulkhead.

[0005] Secondly, embodiments of this application provide an outfitting device for a ship's compartment, comprising: The model reconstruction module is used to reconstruct the static geometric model of the ship's cabins when they are only subjected to gravity and buoyancy on water, based on the environmental point cloud data, rigid body motion data of the hull, and elastic strain data of the bulkheads in the state of the ship's cabins on water. The plate segmentation module is used to segment the bulkhead surface based on the static geometric model and the preset ship vibration mode diagram, and generate multiple decorative plate geometric models and the corresponding installation points of each decorative plate geometric model; The connector generation module is used to generate a connector model corresponding to the installation point based on the vibration spectrum of the installation point in the static geometric model. The result generation module is used to generate outfitting design results based on the geometric model of the decorative panel, the mounting points, and the connector model.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application. Those skilled in the art can make adjustments as needed to suit specific application scenarios. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not the entire structure.

[0012] It should be noted that the execution subject of the following method embodiments can be the outfitting device of a ship's cabin. This device can be implemented as part or all of an electronic device through software, hardware, or a combination of software and hardware. Optionally, the electronic device can be a computer, mobile phone, tablet, or portable device, or it can be an independent server or server cluster, etc. The specific type of electronic device is not limited in the embodiments of this application.

[0013] Figure 1 This is a schematic flowchart illustrating a method for outfitting a ship's compartment, as provided in an embodiment of this application. Figure 1 As shown, the method may include: S101. Based on the environmental point cloud data of the ship's cabins in the water state, the rigid body motion data of the hull, and the elastic strain data of the bulkheads, reconstruct the static geometric model of the ship's cabins after they are subjected to only gravity and buoyancy in the water.

[0014] In this embodiment, modeling is performed using measurement data of the ship in its waterborne state. Specifically, when the ship is submerged, environmental point cloud data of the ship's cabins can be acquired using sensors (such as lidar) deployed within the cabins; rigid body motion data of the hull can be acquired using an inertial measurement unit deployed at the hull center; and elastic strain data of the bulkheads under waterborne conditions can be acquired using sensors (such as fiber Bragg grating sensors) deployed at key points of the bulkheads. The aforementioned environmental point cloud data, rigid body motion data, and elastic strain data are fused and calculated. Using Lie group manifolds and modal superposition methods, the rigid body sway and elastic vibration of the ship's cabins are extracted from the environmental point cloud data, preserving the static geometric model of the ship's cabins under only the influence of gravity and buoyancy in the water. This static geometric model can represent the actual state of the ship's cabins when in service on water, considering the possible mid-arching or sagging deformation of the hull beams under floating conditions. This provides an accurate data foundation for subsequent outfitting design, which can then serve as a benchmark to drive the subsequent outfitting design.

[0015] S102. Based on the static geometric model and the preset ship vibration mode diagram, the bulkhead surface is segmented to generate multiple decorative panel geometric models and the corresponding installation points of each decorative panel geometric model.

[0016] This includes obtaining ship vibration modal diagrams under wave and vibration conditions, which can be obtained through finite element analysis of the ship. By analyzing the ship's vibration modal diagrams, the vibration conditions that the ship's compartments may experience in the water can be predicted. Based on these vibration conditions, the bulkhead surfaces of the obtained static geometric model can be segmented. For example, during segmentation, the segmentation lines should be located in the vibration node region as much as possible. In this way, the resulting decorative panel geometric model can resist vibrations during water service to a certain extent, reducing the risk of cracking at the joints of the decorative panels.

[0017] In addition, for each decorative panel geometry model, the number and location of the required installation points can be determined in the corresponding bulkhead area based on its size, weight, and stress requirements.

[0018] S103. Generate the connector model corresponding to the installation point based on the vibration spectrum of the installation point in the static geometric model.

[0019] In this embodiment, a corresponding connector model can be designed for each installation point. The vibration spectrum of each installation point in the static geometric model can be obtained using the ship's vibration modal diagram. Combined with the vibration spectrum of the installation point, the corresponding connector model can be designed. For example, the connector model generated at locations of severe vibration can be a high-damping porous structure (i.e., a soft connection), while the connector model generated at critical stress points can be a high-stiffness truss structure (i.e., a rigid connection).

[0020] By designing a connector model that matches the vibration spectrum of each installation point, the problem of local resonance with the ship can be better addressed while ensuring a stable connection of the decorative panel, thus further reducing the risk of cracking after the installation of the decorative panel.

[0021] S104. Based on the geometric model of the decorative panel, the installation points, and the connector model, generate the outfitting design results and associate and store the outfitting design results with the bulkhead.

[0022] The outfitting method for ship compartments provided in this application reconstructs a static geometric model of the ship compartment under the influence of gravity and buoyancy in a waterborne state. This static geometric model serves as a benchmark to drive subsequent outfitting design, solving the technical problem of traditional methods that neglect the inability to install decorative panels on water due to hull arching or sagging deformation caused by shore measurement data. Furthermore, by designing decorative panels using a static geometric model and ship vibration modal diagrams, the impact of ship vibration on the decorative panels is fully considered, reducing the risk of cracking at the joints of the decorative panels under vibration conditions. In addition, by designing connectors based on the vibration spectrum of the installation points in the static geometric model, the connectors can better cope with resonance issues with the ship, further improving the reliability of the outfitting design results and reducing the problem of rework due to improper outfitting design results, thereby improving the outfitting efficiency of ship compartments.

[0023] In one embodiment, S101 may optionally include: determining the rigid body motion components based on rigid body motion data using a Lie group manifold; determining the elastic flutter components based on elastic strain data using a modal superposition method; and removing the rigid body motion components and elastic flutter components from the environmental point cloud data to obtain a static geometric model of the ship's cabins on water under the influence of only gravity and buoyancy.

[0024] Specifically, the rigid body motion of the hull under wave interference is described using Lie group manifolds, and the high-frequency elastic flutter of the bulkheads under wave disturbance is described using modal superposition. The instantaneous spinor of the hull is obtained by solving the rigid body motion data, and the rigid body motion components are determined based on the Lie group manifolds and the instantaneous spinor. The modal coefficients of each order of vibration are obtained by solving the elastic strain data. Based on the modal coefficients and corresponding mode shape functions of each order of vibration, the elastic flutter of each order is determined, and the elastic flutter components are obtained by superimposing the elastic flutter of each order using the modal superposition method.

[0025] Rigid body motion components and elastic flutter components are removed from the environmental point cloud data, and residual noise is filtered out from the processed environmental point cloud data by time-domain integration, resulting in a static geometric model of the ship's cabins on water under the action of only gravity and buoyancy.

[0026] As an alternative implementation, rigid body motion components, elastic flutter components, and residual noise in environmental point cloud data can be removed through the following process: ; in, For instantaneous kinetic spinor, Let i be the mode shape function of the i-th order vibration. These are the modal coefficients of the i-th order vibration calculated from the elastic strain data. For the reconstructed static geometric model of the ship's compartments, For environmental point cloud data, N represents the vibration order and T represents the calculation time.

[0027] In this embodiment, the rigid body motion components are determined by Lie group manifolds, and the elastic flutter components are determined by modal superposition. The rigid body motion components, elastic flutter components, and residual noise are removed from the environmental point cloud data. This model is a smooth, accurate static geometric model that retains the true deformation of the ship's cabins on water caused only by gravity and / or buoyancy. It considers the mid-arch or mid-sag deformation of the hull beams in the floating state on water, and uses this as a benchmark to drive the subsequent outfitting design, providing a data basis for the installation of decorative panels on water.

[0028] In one embodiment, optionally, S102 may include: obtaining the vibration acceleration distribution of the bulkhead surface based on the ship's vibration modal diagram, converting the vibration acceleration distribution into a potential energy field, and superimposing the potential energy field onto the static geometric model; dividing the bulkhead surface of the static geometric model after superimposing the potential energy field with the dividing line located in the vibration node region as the optimization objective, generating multiple decorative panel geometric models; and determining the installation point corresponding to each decorative panel geometric model based on the mechanical load requirements of each decorative panel geometric model.

[0029] Specifically, by analyzing the ship's vibration modal diagrams, the potential vibration acceleration distribution on the bulkhead surface under water conditions can be predicted. This vibration acceleration distribution is converted into a potential energy field. Regions with high vibration have high potential energy and can be considered antinodes, while regions with low vibration have low potential energy and can be considered nodes. The potential energy field is superimposed on a static geometric model, and the bulkhead surface of the static geometric model after superimposing the potential energy field is segmented with the optimization objective of the segmentation line falling within the node region. This drives the segmentation line to avoid antinodes as much as possible and fall within the node region, ensuring that the decorative panel seams avoid high-stress areas. By segmenting the bulkhead surface in this way, a model can be generated such as... Figure 2 The geometric models of the multiple decorative panels shown are related to the vibration potential energy of the bulkhead surface, and their edge lines are all located in the vibration node region, thereby reducing the risk of cracking at the joints after the decorative panels are installed.

[0030] In addition, for each decorative panel geometry model, the number and location of the required installation points in the corresponding bulkhead area can be determined according to its mechanical load requirements (including dynamic and static mechanical load requirements).

[0031] Alternatively, for each decorative panel geometric model, its corresponding installation point can be determined according to the following process: based on the mechanical load requirements and bulkhead structural characteristics of the decorative panel geometric model, the initial installation point is determined; based on the vibration spectrum of the initial installation point in the static geometric model, the initial installation point is adjusted to obtain the final installation point of the decorative panel geometric model.

[0032] By analyzing the structural characteristics of the bulkhead, we can identify areas on the bulkhead surface unsuitable for openings and areas suitable for openings. For example, welds and structural openings are unsuitable, while high-stiffness areas such as stiffeners and trusses are suitable. When designing installation points, we should avoid these unsuitable areas and select points from the suitable areas that meet the mechanical load requirements of the decorative panel's geometric model as initial installation points. After determining the initial installation points, we can analyze their vibration spectrum. Based on the analysis results, we can select initial installation points located in the antinode region of the vibration wave and adjust their positions to the nodes with lower vibration in the corresponding bulkhead region. Of course, during the adjustment process, we must ensure that the adjusted installation points still meet the mechanical load requirements of the decorative panel's geometric model.

[0033] This method ensures that the installation points corresponding to the determined geometric model of the decorative panel can avoid high-stress areas as much as possible, while meeting the mechanical load requirements of the geometric model of the decorative panel, thereby reducing the risk of cracking after the decorative panel is installed.

[0034] To ensure that the designed decorative panel geometry can pass smoothly through space-constrained ship cabin passageways during subsequent installation, alternatively, such as Figure 3 As shown, the geometric model of the decorative panel can also be generated according to the following process: S301. Obtain the vibration acceleration distribution on the surface of the bulkhead based on the ship's vibration modal diagram, convert the vibration acceleration distribution into a potential energy field, and superimpose the potential energy field onto the static geometric model.

[0035] S302. Taking the location of the dividing line in the vibration wave node region as the optimization objective, the surface of the bulkhead of the static geometric model after the superimposed potential energy field is divided to generate multiple initial decorative panel geometric models.

[0036] S303. Collision detection is performed on the initial decorative panel geometry model in the passageway configuration space of the ship's cabin.

[0037] In this embodiment, a triangular mesh model of obstacles (such as bulkheads, pipes, equipment, etc.) within the ship's cabin passageways and its hierarchical bounding boxes can be constructed, along with a bounding box for the initial decorative panel geometry model. This simulates the movement of the initial decorative panel geometry model along a preset transport path. At each sampling point of the initial decorative panel geometry model, a rapid intersection detection is first performed using the hierarchical bounding boxes. If the bounding boxes intersect, a finer detection is then performed using a triangular mesh intersection algorithm to determine whether the initial decorative panel geometry model intersects with the triangular meshes of the obstacles. If there are no collisions at any sampling point, the initial decorative panel geometry model is determined to have passed the collision detection; if any sampling point collides, the collision detection is deemed to have failed, and the initial decorative panel geometry model needs to be further segmented.

[0038] S304. If the collision detection fails, the initial decorative panel geometric model is re-segmented with the dividing line located in the vibration nodal region as the optimization objective.

[0039] S305. Use the sub-models obtained after segmentation as new initial decorative panel geometric models, and continue to execute S303 above until all sub-models pass the collision detection to obtain the final decorative panel geometric model.

[0040] If the initial decorative panel geometry fails the collision detection, a second segmentation is performed, with the segmentation line located in the vibration nodal region as the optimization objective. This drives the segmentation line to avoid vibration antinode regions as much as possible, thus ensuring that the seams of the segmented sub-models avoid high-stress areas. Furthermore, the segmented sub-models are used as new initial decorative panel geometry models, and collision detection is performed on these sub-models within the passageway configuration space of the ship's cabins until all sub-models pass the collision detection, resulting in the final decorative panel geometry model.

[0041] By performing collision detection on the segmented initial decorative panel geometric model in the passageway configuration space of the ship's cabin, the initial decorative panel geometric model that fails the collision detection continues to be segmented a second time. In this way, it can be ensured that the final generated decorative panel geometric model can pass smoothly through the passageway of the ship's cabin during the transportation process, reducing the situation where the decorative panel cannot be transported and needs to be reworked, and improving outfitting efficiency.

[0042] In one embodiment, optionally, the process of generating a connector model corresponding to the mounting point based on the vibration spectrum of the mounting point in the static geometric model may include: determining the required mechanical impedance characteristics of the mounting point based on the load requirements of the mounting point and the vibration spectrum of the mounting point in the static geometric model; and generating the corresponding connector model based on the mechanical impedance characteristics.

[0043] In this embodiment, the connector can be considered as a mechanical filter connecting the hull and the decorative panel. For each mounting point, the stiffness value required by the connector model is calculated based on the load requirements at that point. These load requirements can include the static load generated by the self-weight of the decorative panel's geometric model and the dynamic inertial force caused by hull swaying. The vibration spectrum of the mounting point is analyzed, extracting characteristic parameters such as the dominant frequency, peak amplitude, and half-power bandwidth. Based on the half-power bandwidth method and the aforementioned characteristic parameters, the required equivalent damping ratio for that mounting point is estimated. The required damping characteristics should enable the connector to effectively dissipate vibration energy near the dominant frequency, avoiding resonance amplification.

[0044] Using the aforementioned stiffness values ​​and damping requirements as mechanical impedance characteristics, a corresponding connector model is generated based on these characteristics using a topology optimization algorithm. (See also...) Figure 2 When the mechanical impedance characteristics required at the installation point are predominantly stiff over a wide frequency range (i.e., high load requirements and low vibration), a high-stiffness truss structure connector is generated. When the mechanical impedance characteristics required at the installation point are predominantly damping over a wide frequency range (i.e., high vibration energy), a high-damping porous structure connector is generated. If both requirements are significant, a gradient structure can be generated to meet stiffness and damping requirements at different locations. Subsequently, a connector model can be printed using 3D printing based on the connector structures obtained above.

[0045] For each installation point, a corresponding connector model is designed according to its required mechanical impedance characteristics. On the basis of stable connection of the decorative panel, it can better deal with the local resonance problem with the ship and further reduce the risk of cracking after the installation of the decorative panel.

[0046] In a swaying environment on water, to facilitate the installation of decorative panels by workers, visual markers can optionally be placed on the bulkheads of the ship's compartments. These visual markers uniquely identify the bulkheads and can be any type of graphic code, such as a QR code or barcode. During the installation of decorative panels on the target bulkhead, workers scan the visual markers on the target bulkhead using MR glasses. The MR glasses acquire the identification information of the target bulkhead corresponding to the visual marker, generate an information retrieval command based on this information, and send the command to an electronic device. This information retrieval command may include the identification information of the target bulkhead.

[0047] The electronic device receives an information acquisition command from the MR glasses, retrieves the outfitting design results of the target bulkhead based on the identification information carried in the command, and sends these results back to the MR glasses. The MR glasses display the outfitting design results and guide workers to install decorative panels based on them. For example, such as... Figure 4As shown, MR glasses can display the installation guide lines and installation points for each decorative panel's geometric model, allowing workers to easily follow the instructions. This simplifies the installation process and improves outfitting efficiency.

[0053] Based on the above embodiments, optionally, the plate segmentation module 502 is also used to determine the initial installation point for each decorative plate geometric model based on the mechanical load requirements and bulkhead structural characteristics of the decorative plate geometric model; and to adjust the initial installation point based on the vibration spectrum of the initial installation point in the static geometric model to obtain the final installation point corresponding to the decorative plate geometric model.
