[0073] After connecting the transmission unit to be connected in a connection option of the auxiliary modeling menu and the given transmission unit, increase the connection coefficient in the connection option.

[0074] The other technical features of this embodiment are exactly the same as those of embodiment 4.

[0075] In a specific embodiment, the present invention is used to perform intelligent auxiliary modeling on the configuration of a ship transmission device, wherein the method for constructing a basic unit library and an auxiliary modeling library is as follows:

[0076] 1. According to the existing transmission forms of ship transmission devices, summarize the various transmission units and their commonly used connection (shaft connection, meshing connection) units, save the graphics and parameter information of each transmission unit and its corresponding connection unit, and preliminarily establish an auxiliary modeling library that can characterize the unit connection relationship.

[0077] Among them, the transmission unit types are specifically divided into three categories: power units, gears and other units. The power units mainly include diesel engines, gas turbines, motors, single-cylinder steam turbines, propellers, etc. The gears include herringbone gears, helical gears, bevel gears and planetary gear trains. Other units mainly include bearings such as sliding bearings and rolling bearings, clutches such as SSS clutches, gear flank clutches, friction clutches, and couplings such as diaphragm couplings and gear couplings.

[0078] The parameter information mainly includes basic unit parameters (length, width, height, number of teeth, module, etc.), power parameters (torque, power, speed, etc.) and primitive parameters (connection anchor points, picture information, etc.). The unit information is saved in JSON format to form a basic unit library; the commonly used connection units of the transmission unit are analyzed, such as the main engine connected to the clutch / coupling through the shaft, the gears connected to the gears through meshing, and the gears connected to the bearings through the shaft.

[0079] The connection relationship is stored in the auxiliary modeling library to complete the preliminary construction of the auxiliary modeling library. This connection relationship can be expressed as:

[0080] R 主机-联轴器 =φ(Engine.json, Coupling.json, S, r)

[0081] Among them, R 主机-联轴器 It indicates that the host and the coupling are connected. The two unit information are respectively represented in Engine.json and Coupling.json. S represents the connection method through the shaft, G represents the connection method through meshing, and r represents the connection coefficient, that is, the number of times the modeler connects the host and the coupling.

[0082] Formed as Figure 2 The basic unit library file structure is shown.

[0083] The following is an example of the gas turbine JSON format: including unit connection point information, power, torque, speed, spatial position, and primitive parameters.

[0084]

[0085]

[0086] The auxiliary modeling library is mainly established by analyzing the corresponding connection units of each transmission unit, and persisting this relationship in the XML file. For example, the connection unit relationship established by the gas turbine through the shaft connection is: Its corresponding "gas turbine.xml" is as follows Figure 3 shown.

[0087] R 燃气轮机-膜片联轴器 =φ(gas turbine.json, diaphragm coupling.json, S, 0)

[0088] R 燃气轮机-摩擦离合器 =φ(gas turbine.json, friction clutch.json, S, 0)

[0089] The connection unit relationship established by the meshing connection of the herringbone gears is:

[0090] R 人字齿轮-人字齿轮 =φ(herringbone gear.json, herringbone gear.json, G, 0)

[0091] R 人字齿轮-齿腹离合器 =φ(herringbone gear.json, tooth flank clutch.json, G, 0)

[0092] 2. The auxiliary modeling library is gradually improved by preserving the modeling habits of modelers, and the modeling habits of modelers are reproduced through the continuously improved auxiliary modeling library to complete the construction of the configuration intelligent prompt method.

[0093] The connection factor is the number of times the modeler connects two drive units (such as a main machine and a coupling).

[0094] During the modeling process, when two units C1 and C2 are connected by axis or meshing, if the auxiliary modeling library has the connection information of these two units, the connection coefficient r is increased to r+1, thereby achieving the purpose of preserving the modeling habits of the modeler.

[0095] During the modeling process, when two units C1 and C2 are connected by shaft or meshing, if the auxiliary modeling library does not have the connection information of the two units, add R C1-C2 To the auxiliary modeling library.

[0096] Furthermore, for a specific transmission unit, transmission units having a connection relationship with the transmission unit can be screened out in the auxiliary modeling library according to the size of the connection coefficient for selection by the modeler, thereby realizing the construction of an intelligent auxiliary modeling method.

[0097] For example, the connection coefficients can be arranged in descending order so that modelers can find the most commonly used connection relationships at the top for quick selection.

[0098] 3. Visualize the intelligent assisted modeling method in the process of ship transmission configuration.

[0099] Intelligent auxiliary modeling is mainly used to prompt modelers about the connection units of transmission units, so that modelers can configure the entire transmission device by establishing several initial transmission units. The visualization method is mainly completed using container controls and artboard controls. First, use container controls to import the scalable vector graphics corresponding to each transmission unit described in the JSON file in the basic unit library to form a transmission unit library, such as Figure 5 As shown, secondly, use the canvas control to display the graphics of each transmission unit from the unit list displayed by the container control into the canvas control, thus completing the modeling of the initial transmission unit.

[0100] Again, by docking the initial transmission unit, the transmission unit graphic information is parsed to calculate its anchor point position, and an indicator icon pops up at the connection anchor point through the container control. After docking the indicator icon, the auxiliary modeling library is queried, and a list of connectable transmission units (auxiliary modeling menu) is popped up in the order of connection coefficients through the container control for modelers to choose. At the same time, by clicking the anchor point, the connection unit with the largest (or arbitrary) connection coefficient is automatically created. This greatly improves the modeling efficiency, such as Figure 7 This is the transmission configuration obtained through intelligent prompts. Specific implementation method 6
