Specific embodiment
As shown in Figure 1, a kind of vehicle automation modeling method for CAE emulation, which is characterized in that including walking as follows
It is rapid:
Step 1: setting for Full Vehicle Modelling CAD (CAD Computer Aided Design) data and
Corresponding structure BOM (bill of materials Bill of Material) file, in CAE (computer-aided engineering computer
Aided engineering) above-mentioned BOM file is imported in modeling software；The common format of BOM file is XML format.
In step 1, for the BOM file of importing, the COG(center of gravity Center of of part in BOM file is calculated
Gravity) data, and COG data information is written in BOM file.
Step 2: as shown in Fig. 2, the structure allocation list based on setting, carries out structure weight to the BOM file obtained in step 1
Group, the BOM file after being recombinated, for subsequent calls.
In step 2, described structure allocation list is closed according to the mapping that user needs to establish user structure and system prototype structure
System.
Step 3: importing geometric data, so as to carry out matching corresponding for each geometric data and BOM row, construct completely whole
Vehicle CAD model, and grid dividing is carried out to geometric data；Attribute assignment is carried out to each part；By grid dividing data, attribute
In BOM file after assignment data write-in recombination.
In step 3, as shown in figure 3, carrying out grid according to size of mesh opening specification and quality criteria information to geometric data and drawing
Point, the grid to conform to quality requirements is generated, grid file information is written in BOM, is loaded directly into grid text will pass through BOM
Part.
In step 3, as shown in figure 4, being called based on each part material therefor information, metal plate thickness information in BOM file
Material depot generates attribute card, carries out attribute assignment to each part.
Step 4: as shown in figure 5, generating connection unit according to link information data file；Matched based on connection unit, assembly
It sets table and carries out system assembly, form model, such as four-door two-lid system, bodywork system etc.；By connection unit, system assembly information
In BOM file after write-in recombination.
In step 4, described connection unit includes solder joint connection unit, solder design unit, glue connection unit, is bolted
