It applies example and this is no longer repeated one by one.
Fig. 2 is that a kind of temperature field of engine provided by the embodiments of the present application determines the flow chart of method, referring to FIG. 2,
This method comprises the following steps.
Step 201: terminal obtains the group result and group names of engine the machine and water jacket, and obtains analysis mould
Plate.
It should be noted that using the parameter arrived, the acquisition when analysis template is used to store the temperature field of determining engine
Engine the machine and water jacket group result and group names with analysis template in group result and group names it is identical.
As an example, analysis personnel can in advance be grouped engine the machine and water jacket, and can in grouping
To be grouped according to code requirement and be named to grouping, and pass through specified operation by group result and to the name of grouping
It is input to terminal.The specified operation can be clicking operation, slide, voice operating, input operation etc..Alternatively, terminal
Engine body and water jacket can also be grouped and named, to be sent out according to history classification results and naming method
The group result and group names of motivation the machine and water jacket.
For example, can by engine the machine and who to be divided into three groups and be named as cylinder cap, cylinder body and cylinder pad, can be in cylinder cap
Including cylinder cap ontology, cylinder cover water jacket, valve, valve retainer, conduit etc., cylinder body may include cylinder body ontology, cylinder body water jacket, cylinder sleeve
It may include cylinder pad body, cylinder pad water hole etc. Deng, cylinder pad.
In order to guarantee that subsequent analysis model can identify the grouping of engine body and water jacket, group result and group names
It needs consistent with the group result and group names analyzed in template.
It should be noted that the analysis template is Electronic forms Excel template.It that is to say, which can be base
In the template that Excel is generated.The analysis template may include the file road of the surface grids of the cylinder cap of engine, cylinder body and cylinder pad
Diameter, the folder path of thermal boundary file, the size of the volume mesh and body fitted anisotropic mesh that are respectively grouped, cylinder cap, cylinder body and cylinder pad point
Not corresponding coolant temperature and pressure, the density of engine body, conductivity material parameter, the inlet and outlet volume of cooling jacket
Flow, the thermal boundary of the gray iron of engine and cylinder pad, combustion chamber and machine oil cooling boundary, the thermal boundary of valve, valve seating
The thermal boundary of circle and the thermal boundary of conduit.
As an example, the parameter analyzed in template can be arranged in advance, refer to when receiving editor based on analysis template
When enabling, the parameter in analysis template can be edited.The edit instruction can have analysis personnel to trigger by specified operation,
The edit instruction may include modification instruction, delete instruction, addition instruction etc..
Step 202: engine body and water jacket are carried out gridding processing by terminal.
Since the construction of engine is complex, for the ease of the temperature field of subsequent determining engine, terminal can be to hair
Motivation ontology and water jacket carry out gridding processing.
As an example, engine body and water jacket can be grouped due to above-mentioned, it can be according to grouping
As a result gridding processing is carried out to engine body and water jacket, and engine body and water jacket are carried out gridding processing by terminal
Operation can be with are as follows: the cylinder cap of engine, cylinder body and cylinder pad are carried out gridding processing, obtain cylinder cap grid, cylinder body grid and cylinder
Grid is padded, cylinder cap grid includes cylinder cap essence grid, cylinder cover water jacket grid, valve grid, valve seating grid and conduit grid, cylinder
Volume mesh includes cylinder body essence grid, cylinder body water jacket grid and cylinder sleeve grid, and it includes cylinder advance capital for volume mesh and cylinder pad that cylinder, which pads grid,
Water hole grid.
As an example, terminal can carry out surface grids when carrying out gridding processing to engine body and water jacket
It divides, volume mesh division can also be carried out.And grid can be triangular mesh, quadrilateral mesh or other polygonal mesh.
As an example, terminal can carry out gridding processing to engine body and water jacket according to specified size,
Engine body and water jacket can be divided into specified quantity grid.The specified size and specified quantity can be arranged in advance,
For example, the specified size can be 8mm (millimeter) * 8mm, 4mm*4mm etc..The specified quantity can be 1000,2000
Etc..
Step 203: engine body and water jacket of the terminal based on gridding, and analysis template, it is true by analysis model
Determine the temperature field of engine.
It it should be noted that analysis model is used to carry out temperature field analysis to engine, and include analysis in analysis model
Entire flow (complete analytical procedure) when the temperature field of engine.
It can be seen from the above, using the parameter arrived when analysis template can be used for storing the temperature field of determining engine, therefore,
Engine body and water jacket of the terminal based on gridding, and analysis template, the temperature field of engine is determined by analysis model
When, the parameter in analysis template can be called by analysis model, and the engine body of gridding and water jacket are divided automatically
Analysis, so that it is determined that the temperature field of engine.
In some embodiments, due to include in analysis template thermal boundary file folder path, terminal can be with
The folder path that thermal boundary file is directly based upon during determining engine temperature field by analysis model carries out hot side
The mapping on boundary.Certain terminal can also pass through analysis based on the engine body of gridding and the water jacket, and analysis template
Before model determines the temperature field of engine, the mapping of thermal boundary is carried out.
As an example, the thermal boundary file based on unit number can be passed through mapping conversion by analysis model by terminal
For the thermal boundary file based on coordinate, it should be used to determine the temperature field of the engine based on the thermal boundary file of coordinate.
It should be noted that the entire flow in the temperature field for the analysis engine for including in analysis model can be with reference to correlation
Technology, the embodiment of the present application no longer repeat this one by one.
Step 204: terminal shows the temperature field of engine.
In order to make analysis personnel recognize the temperature field of engine, terminal can be shown behind the temperature field for determining engine
Temperature field.
As an example, when analysis personnel determine engine temperature field it is improper when, can be repaired by edit instruction
Change the parameter in analysis template, and triggering terminal re-execute the steps 203 operation.
In the embodiment of the present application, the available engine the machine of terminal and the group result and group names of water jacket, with
And analysis template is obtained, and engine body and water jacket are subjected to gridding processing, engine body and water based on gridding
Set, and analysis template, the temperature field of engine is determined by analysis model.Due to engine the machine of acquisition and point of water jacket
Group result and group names are identical as the group result and group names analyzed in template, to guarantee that analysis model can identify
The grouping of engine body and water jacket, and be that can determine the temperature field of engine by analysis template and analysis model, it simplifies
Analytical procedure, without analyzing overstaffed participation, the probability for greatly improving working efficiency, reducing analysis mistake, Er Qieneng
Guarantee the consistency that result is analyzed between different analysis projects teacher.
