[0001] This invention relates to the fields of mechanical design and computer-aided conceptual technology, specifically to a design system and method for ship transmission devices. Background Technology
[0002] Currently, most commercial computer-aided design software models based on complete, precise, unique, and quantitative mathematical descriptions, which suffers from a lack of support for top-down design and conceptual modeling. In the field of ship transmission design, there is a lack of a design system and method to significantly improve modeling efficiency. The main problems are: the lack of a method for saving transmission system schemes and a transmission scheme database; the modeling method relying on designers manually connecting individual transmission units still has significant room for improvement in efficiency; and the lack of a transmission unit recommendation method to help or guide designers to quickly select the required transmission units and improve modeling efficiency. Summary of the Invention
[0003] This invention proposes a design system and method for ship transmission devices, which addresses the problems of lack of design tools, limited modeling methods, and low modeling efficiency in ship transmission systems.
[0004] This invention provides a design system for ship transmission devices, comprising:
[0005] The recommended unit library module is used to define the attribute information of each transmission unit in the ship's transmission system, recommend multiple matching units to different transmission units, and build a recommended unit library.
[0006] The transmission component library module combines and connects different transmission units to form transmission components and builds a transmission component library.
[0007] The transmission model library module establishes a classic ship transmission model, records the attribute information of each transmission unit in the ship transmission model, and constructs a transmission model library.
[0008] The modeling and drawing module is used to connect transmission units to matching units selected from the recommended unit library, to connect two transmission units that are combined to form a transmission component, and to edit the transmission model selected from the transmission model library.
[0009] Furthermore, the recommendation unit library module includes:
[0010] The unit analysis module is used to obtain the structure of multiple different ship transmission systems and decompose them into multiple transmission units;
[0011] The attribute definition module analyzes the common or unique attributes of each transmission unit to determine the attributes of each transmission unit, and recommends multiple matching units to be combined with each transmission unit based on the attributes of each transmission unit. Each transmission unit has a library of recommended units that match it. The library of recommended units is displayed in a multi-page format, with multiple matching units of the transmission unit to be combined displayed on the first page of the library.
[0012] The common attributes include graphical parameters and physical parameters; the unique attributes include geometric parameters.
[0013] Furthermore, the modeling and drawing module includes:
[0014] The unit display module is a display carrier used to represent the transmission unit in the form of a simplified diagram, providing a visual modeling environment;
[0015] The unit editing module is used to perform alignment, rotation, deletion, copying, cutting, and size modification operations on the transmission unit;
[0016] The connection module is used to establish a connection at the interface between the transmission units, thereby realizing the connection between the transmission units.
[0017] Furthermore, when a transmission unit is selected in the recommended unit library module, the unit display module creates an instance of that transmission unit and displays multiple matching units recommended for that transmission unit in the recommended unit library. When one of the matching units is selected, the unit display module creates an instance of the selected matching unit and uses the connection module to connect the transmission unit to be combined with the selected matching unit.
[0018] Furthermore, the recommendation unit library constructed by the recommendation unit library module and the transmission component library constructed by the transmission component library module are interconnected;
[0019] When a transmission component is selected in the transmission component library using the transmission component library module, the attribute information of the corresponding matching unit is indexed in the recommended unit library according to the names of the multiple transmission units that make up the transmission component. The display position of the matching unit in the unit display module is determined according to the relative position between the multiple matching units. Then, the connection module is used to establish a connection between the matching units according to the connection interface information of each matching unit.
[0020] Furthermore, when a transmission model is selected in the transmission model library using the transmission model library module, the transmission model is displayed using the unit display module.
[0021] Furthermore, when a transmission unit is selected in the recommended unit library, the unit display module creates an instance of that transmission unit, and the instance of that transmission unit is identical to the original transmission unit except for its name attribute.
[0022] When the transmission unit is connected to a recommended matching unit, the matching unit that is combined with it is displayed according to the position of the connection interface selected on the transmission unit.
[0023] Furthermore, the attribute information of the transmission unit includes the name, input interface, output interface, and size of the transmission unit;
[0024] The common attributes among the various transmission units include the name of the transmission unit, the number of input interfaces, the number of output interfaces, the location of the input interfaces, and the location of the output interfaces.
[0025] The common attributes among the various transmission units are determined by the connection relationship between the various transmission units and the location of the connection points;
[0026] The common attributes among the various transmission units and the attribute information of each transmission unit are linked through the name of the transmission unit.
[0027] The information contained in the transmission component library includes the number of interfaces of the transmission units that have been connected, the relative positions between the transmission units, and the names of the transmission units.
[0028] Furthermore, the attribute definition process of the attribute definition module is as follows:
[0029] The attribute definition method for the transmission unit is as follows:
[0030] A={α,β} (1)
[0031] Where α represents a common attribute, β represents a unique attribute, and “=" represents the binding relationship between the unit and the attribute;
[0032] The method for defining the properties of transmission components:
[0033] Group1 = {A, B, δ} (2)
[0034] A and B are two transmission units that make up the transmission component Group1;
[0035] δ is an attribute of the transmission component, used to store the connected interfaces and relative position coordinates of A and B;
[0036] Once the number of interfaces of the transmission unit is determined, a connectability attribute switch needs to be defined for each transmission unit interface according to the connection form between the transmission units. Only when the connectability attribute switch of the transmission unit interface is in the open state is another transmission unit allowed to establish a connection to that transmission unit.
[0037] This invention also provides a design method for ship transmission devices, comprising the following steps:
[0038] Define the attribute information of each transmission unit in the ship's transmission system, recommend multiple matching units to different transmission units, and build a recommended unit library;
[0039] By combining and connecting different transmission units to form transmission components, a transmission component library is constructed.
[0040] By establishing a classic ship transmission model, recording the attribute information of each transmission unit in the ship transmission model, and constructing a transmission model library;
[0041] Connect the transmission unit to the selected matching unit;
[0042] Connect two transmission units that are combined and connected to form a transmission component;
[0043] The editor selects a transmission model from the transmission model library.
[0044] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0045] This invention solves the problem of rapid construction of ship transmission system topology models using a database approach. It recommends multiple matching units to different transmission units, forming a recommended unit library; it also combines and connects different transmission units to form a transmission component library, and establishes a classic ship transmission model, forming a transmission model library. When designing ship transmission devices, users select the recommended unit library and transmission component library they need. After selecting the required units, components, or models, they can then use the modeling and drawing module to combine, connect, or edit them, thus achieving rapid construction of the ship transmission system's topology. Furthermore, by analyzing the topology model established for the transmission components, a transmission system design scheme can be quickly obtained, greatly improving design efficiency and laying the foundation for subsequent independent innovative design.

[0050] Figure 4 This is a schematic diagram of the F124 transmission device in an embodiment of the present invention. Detailed Implementation
[0051] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. However, it should be understood that the scope of protection of the present invention is not limited to the specific implementation.
[0052] like Figure 1 As shown, this invention provides a design system for ship transmission devices, including a recommended unit library module for defining the attribute information of each transmission unit in the ship transmission system, recommending multiple matching units to be combined with different transmission units, and constructing a recommended unit library; a transmission component library module for forming transmission components by combining and connecting different transmission units, and constructing a transmission component library; a transmission model library module for building a classic ship transmission model, recording the attribute information of each transmission unit in the ship transmission model, and constructing a transmission model library; and a modeling and drawing module for connecting transmission units with matching units selected from the recommended unit library, connecting two transmission units combined to form a transmission component, and editing the transmission model selected in the transmission model library.
[0053] In this invention, according to the design requirements of the ship's transmission system, after selecting a matching unit from the recommended unit library using the recommended unit library module, the modeling and drawing module is used to establish a connection between the transmission unit and the matching unit; after selecting a transmission component from the transmission component library using the transmission component library module, the modeling and drawing module is used to establish a connection between two transmission units that are combined to form a transmission component; after selecting a transmission model from the transmission model library module, the modeling and drawing module is used to edit the selected transmission model. The modeling and drawing module designs and forms the topological relationship model of the ship's transmission system by editing or combining the connected transmission units.
[0054] like Figure 1As shown, the recommended unit library module in this invention includes a unit analysis module, which is used to obtain the structure of multiple different ship transmission systems and decompose them into multiple transmission units respectively; and an attribute definition module, which determines the attributes of each transmission unit by analyzing the common or unique attributes of each transmission unit, and recommends multiple matching units to be combined with each transmission unit according to the attributes of each transmission unit.
[0055] The system consists of multiple matching units forming a recommended unit library, with each transmission unit having its own matching recommended unit library. The recommended unit library is displayed on multiple pages, with the first page showing multiple matching units of the transmission unit to be combined.
[0056] The common attributes include graphical parameters and physical parameters. Graphical parameters include the size, interface, and name of the transmission unit, while physical parameters include the speed, power, and torque.
[0057] Specific attributes include structural or geometric parameters, which specifically include the number of teeth and module of the gear unit, the direction of rotation and coordinates of the host unit, etc.
[0058] The attribute information of the transmission unit includes the name, input interface, output interface, and dimensions of the transmission unit;
[0059] The common attributes among the various transmission units include the name of the transmission unit, the number of input interfaces, the number of output interfaces, the location of the input interfaces, and the location of the output interfaces. Taking the number of interfaces as an example: a propeller only needs one interface, while a bearing needs two. The common attributes among the various transmission units are determined by the connection relationships between them and the location of the connection points. Since both types of transmission units are connected via shaft segments, the interface location is determined to be in the middle of the boundary of the geometric diagram.
[0060] In this invention, the common attributes among the various transmission units and the attribute information of each transmission unit are linked through the name of the transmission unit.
[0061] The attribute definition process of the attribute definition module in this invention is as follows:
[0062] The attribute definition method for the transmission unit is as follows:
[0063] A={α,β} (1)
[0064] Where α represents a common attribute, β represents a unique attribute, and “=" represents the binding relationship between the unit and the attribute;
[0065] For example α={Anchor,Image,Allowincoming,Allowoutcoming,Name},
[0066] β={HelicalAngle,Modulus}.
[0067] Each of the two types of attributes mentioned above can define its sub-attributes and data types, such as:
[0068] Anchor = {p1, p2, p3}, where p1, p2, p3 represent interfaces respectively;
[0069] p1 = {x, y}, where {x, y} represents the relative position coordinates of the interface;
[0070] Allowincoming = true;
[0071] Name = "Hinged Gear", meaning the former is a Boolean value type and the latter is a string value type.
[0072] The method for defining the properties of transmission components:
[0073] Group1 = {A, B, δ} (2)
[0074] A and B are two transmission units that make up the transmission component Group1;
[0075] δ is an attribute of the transmission component, used to store the connected interfaces and relative position coordinates of A and B;
[0076] Once the number of interfaces of the transmission unit is determined, a connectability attribute switch needs to be defined for each interface of the transmission unit according to the connection method between the transmission units. Only when the connectability attribute switch of the interface of the transmission unit is in the open state is another transmission unit allowed to establish a connection to that transmission unit; otherwise, a connection is not allowed.
[0077] As can be seen from the above definition, the switch is only in the open state when Allowincoming = true.
[0078] The recommended unit library in this invention is displayed across multiple pages, with the first page showing multiple matching units for the transmission unit to be combined, and the remaining non-matching units displayed on subsequent pages. Each transmission unit to be combined has a matching recommended unit library. For example, the recommended unit library for the main unit includes, but is not limited to, couplings, other main units, and clutches, while the recommended unit library for the pinion includes, but is not limited to, large gears and bearings.
[0079] like Figure 1As shown, the modeling and drawing module of this invention includes a unit display module, which is used to represent the display carrier of the transmission unit in the form of a simplified diagram and provide a visual modeling environment; a unit editing module, which is used to perform alignment, rotation, deletion, copying, cutting and size modification operations on the transmission unit; and a connection module, which is used to establish connections at the interfaces between transmission units to realize the connection between transmission units.
[0080] This invention achieves rapid model establishment of similar transmission forms in ship transmission systems through the following method:
[0081] (1) When a transmission unit is selected in the recommended unit library module, the unit display module creates an instance of the transmission unit and displays multiple matching units recommended for the transmission unit in the recommended unit library. When one of the matching units is selected, the unit display module creates an instance of the selected matching unit and uses the connection module to connect the transmission unit to be combined with the selected matching unit.
[0082] When a transmission unit is selected from the recommended unit library, the unit display module creates an instance of that transmission unit. The instance and the original transmission unit are identical except for the name. For example, when transmission unit A is converted into transmission unit A created by the unit display module... 1 At that time, transmission unit A 1 Except for the Name attribute, which differs from that of transmission unit A, all other attributes remain the same.
[0083] When the transmission unit is connected to the recommended matching unit, the matching unit that is combined with it is displayed according to the position of the connection interface selected on the transmission unit.
[0084] For example, transmission unit A = {α, β},
[0085] α = {Allowincoming = true,Allowoutcoming = true,Name = "Hinge Gear 1"...}.
[0086] Then transmission unit A 1 ={α 1 ,β 1},
[0087] α 1 ={Allowincoming=true,Allowoutcoming=true,Name="Hinge Gear 2"...},β 1 =β.
[0088] When establishing a connection, matching units are displayed in the corresponding locations based on the selected interface location.
[0089] If the right-side interface of the transmission unit is selected, the matching unit will be displayed on the right side of the transmission unit, and a connection will be established with the interface on the matching unit that is closest to the former.
[0090] Similarly, after selecting a transmission component from the transmission component library, the unit display module generates that instance (Group1 = {A, B, δ}, then instance Group2 = {A}). 1 B 1 ,δ 1}, δ 1 =δ, A 1 The difference between A and A is the same as above.
[0091] At this point, the connection module can establish connections between the basic units based on the connected interface information in the public attributes.
[0092] (2) The recommended unit library constructed by the recommended unit library module and the transmission component library constructed by the transmission component library module are interconnected;
[0093] The transmission component library contains information including the number of interfaces of the established transmission units, the relative positions between the transmission units, and the names of the transmission units. When a transmission component is selected in the transmission component library module, the attribute information of the corresponding matching units in the recommended unit library is indexed based on the names of the multiple transmission units that make up the transmission component. The display position of the matching units in the unit display module is determined based on the relative positions between the multiple matching units. Then, the connection module establishes connections between the matching units based on the connection interface information of each matching unit.
[0094] The matching unit refers to the member of the transmission component. For example, if a gear and a bearing form a transmission component, the bearing member will be displayed first when there is a gear in the unit display module, and the gear will be displayed first when there is a bearing.
[0095] (3) When a transmission model is selected in the transmission model library using the transmission model library module, the transmission model is displayed using the unit display module.
[0096] The above three methods are used to indirectly generate unit copies containing information such as the attributes and interfaces of each transmission unit. Then, according to the design requirements, recommended transmission units are selected, connections are established between transmission units, or the model library model is edited and modified to quickly form a complete topological relationship model of the ship's transmission system.
[0097] Example 2
[0098] This invention also provides a design method for ship transmission systems, including the following steps:
[0099] Step S1: Define the attribute information of each transmission unit in the ship's transmission system, recommend multiple matching units to different transmission units, and build a recommended unit library;
[0100] Step S2: By combining and connecting different transmission units to form transmission components, multiple transmission components constitute a transmission component library, and the transmission component library is constructed.
[0101] Step S3: Establish a classic ship transmission model, record the attribute information of each transmission unit in the ship transmission model, and build a transmission model library;
[0102] Step S4: Connect the transmission unit to the selected matching unit;
[0103] Step S5: Connect the two transmission units that are combined to form a transmission component;
[0104] Step S6: Edit the transmission model selected in the transmission model library.
[0105] Specifically, based on the design requirements of the ship's transmission system, the topological relationship of the ship's transmission system is constructed by selecting a matching unit from the recommended unit library of transmission units and then establishing a connection between the transmission unit and the matching unit; by selecting a transmission component from the transmission component library and then establishing a connection between two transmission units that are combined to form a transmission component; and by selecting a transmission model from the transmission model library and then editing the selected transmission model.
[0106] The technical solutions of the present invention will be described in detail below with reference to specific embodiments.
[0107] 1. For example Figure 2 The diagram shows transmission units related to a ship's transmission system, including main engine, spur gears, bevel gears, planetary gear trains, clutches, couplings, bearings, propellers, and other units.
[0108] 2. For example Figure 3 The diagram shows transmission components related to a ship's transmission system, including combinations such as a gear and two bearings, a main engine and a coupling, and a hydraulic coupling and two bearings.
[0109] The recommended unit library can update the recommendation order based on existing combinations in the transmission component library. For example, if a complex transmission component includes a combination of gears and clutches, the clutch will be prioritized in the recommended unit library for gear transmission units during subsequent modeling.
[0110] Specific implementation: Use object-oriented technology to build a Windows Forms graphical interface based on the .NET framework, use list controls as the carrier for the recommended unit library and transmission component library, and use drawing controls as the carrier for the unit display module in the modeling and drawing module.
[0111] JSON data language is used as a tool to define the transmission unit interface, transmission unit attributes, and dimensions, while SVG vector graphics language is used as the display format of the transmission unit in the unit display module.
[0112] 3. Utilize the unit analysis module to organize and decompose common ship transmission system configurations. For example... Figure 4 The diagram shows the three-stage, two-shaft transmission configuration of the German F124 frigate. Simplified characteristic diagrams of its basic transmission units are drawn and organized into a recommended unit library. The recommended unit library differs for each transmission unit. For example, the recommended unit library homepage for gear units displays bearings and gears, while the recommended unit library homepage for main engines displays couplings, etc.
[0113] The basic parameter attributes, structural parameter attributes, and graphical attributes of each transmission unit are defined using the attribute definition module.
[0114] The basic parameter attributes of the transmission unit are determined, including the number of interfaces, interface coordinates, and whether connection is allowed. For example, the host unit is defined as an interface, the interface coordinates are located at the midpoint of the right boundary of the unit, and connection is allowed but not allowed to be connected.
[0115] The structural attributes of the transmission unit are defined according to the actual mechanical components, including speed and power. For example, gear units also include unique attributes such as number of teeth, module, and pressure angle.
[0116] The graphic attributes are defined according to the dimensions of the actual components corresponding to the transmission unit, including length, width, display scale factor in the unit library, display scale factor in the modeling and drawing area, and whether stretching is allowed.
[0117] The feature diagrams corresponding to the basic transmission units are represented by SVG graphics. A separate JSON file is defined for each transmission unit to store its basic parameters, structural parameters, and graphical parameter attributes.
[0118] Define the corresponding classes and member fields in the .NET Framework, and establish the correspondence between the member items in the list control in the .NET Framework and the corresponding transmission unit properties during initialization.
[0119] 4. Utilize the unit display module as a display carrier for transmission units represented by simplified diagrams, providing a visual modeling environment;
[0120] The unit editing module allows for operations such as moving, aligning, rotating, deleting, copying, cutting, undoing, redoing, and modifying the size of transmission units.
[0121] When there are at least two transmission units in the unit display module, the alignment command can achieve horizontal, vertical, center, left-aligned, and right-aligned alignment of the transmission units.
[0122] Connect the transmission unit using the connection module, and display the connection lines according to the interface defined by the transmission unit;
[0123] When an item is selected in the list control, the drawing control reads the relevant attributes according to the above correspondence and displays an SVG graphic. When combining transmission units, the name, quantity, and coordinates of the connection interface of the established transmission unit are recorded, and XML data format is generated.
[0124] When saved to the transmission component library, a corresponding relationship is established with the item.
[0125] When an item is selected from the transmission component library, the unit display module reads the information in the XML according to the corresponding relationship: it reads the transmission unit name and quantity in sequence, searches for the corresponding item in the recommended unit library and draws the unit in the unit display module, and then reads the connection interface position of each transmission unit in sequence and establishes a connection between the transmission units.
[0126] The design system and method for ship transmission system models of the present invention can determine the form of the transmission system in the conceptual design stage, and realize the rapid modeling of the topological relationship model of the ship transmission system by relying on the recommended unit library, transmission component library, model library and modeling and drawing module.
[0127] Finally, it should be noted that the above-disclosed embodiment is only one specific embodiment of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
