Abstract
The invention relates to a computer aid engineering based technical model property automatic applying method, including that: a finite element simulation analytical mode is built according to a car body three-dimensional structural model; simulation analytic model group information is created according to names of parts of car body structure; a property automatic applying operation interface is called; a car body structure part material and thickness configuration property file is created; the property file is called; and car body structure property information is automatically applied. The invention can automatically apply car body structure finite element simulation analytic model property information, manual operation is substituted, and accuracy is high. According to the configuration file of the model containing group name, material and thickness information, and material and property information of the group are automatically given to the group. Before using a command, a user creates material information and property information by virtue of a car body part information file, and creation of material and property is automatically completed by virtue of a command function button. The name of property is ensured to be consistent with the name of group. The user is guided by an interaction interface to complete the function operation.
Description
Technical field
The invention belongs to rolling stock structural design field, relate to computer-aided engineering technology automatic applying method of model attributes in the body construction simulation process.
Background technology
Be widely used in the body construction performance history based on computer-aided engineering finite element simulation analytical technology at present, because complex structures such as car bodies, parts are more, can reach the hundreds of item.Adopting the simulation analysis technology to carry out in the modelling process, the definition of attribute adopts manual applying method item by item to finish usually, so the definition of attribute will spend a large amount of time, and very easily produces mistake.Given this,,, work out a kind of method of automatic definition structure attribute, replace manual operations at the locomotive car body design feature based on existing simulation analysis environment.It carries out the finite element simulation analysis fast and has bigger help improving the accuracy that modelling efficient and attribute apply.
Summary of the invention
The purpose of this invention is to provide a kind of manual method that applies of body construction simulation analysis model attribute that is used to replace, this method is integrated in the body construction simulation analysis environment by computer-aided engineering technology secondary development environment on the one hand, utilize body construction to have parameter now on the other hand, apply the structure attribute information that simulation analysis model needs fast.
For achieving the above object, the invention provides a kind ofly based on the automatic applying method of computer-aided engineering technology model attribute, it is characterized in that comprising the following steps:
The first step: create the car body three-dimensional model;
Second step: create the finite element simulation analytical model;
The 3rd step: assembly that need to select definition material/attribute;
The 4th step: create property file;
The 5th step: transfer the property operations interface;
The 6th step: transfer property file;
The 7th step: apply attribute, more new material/attribute information mainly comprises the assembly of choosing in the 3rd step is handled one by one, according to material and its corresponding attribute of thickness establishment/renewal, is not updated as assembly, creates attribute again.
The present invention applies body construction finite element simulation analytical model attribute information automatically, replaces manual operations, the accuracy height.The group name that comprises according to model claims, the configuration file of material, thickness information, and with the material (Material) of group, attribute (Property) information is composed to this group automatically.The user sets up material (Material) information by car body components information file before utility command, and attribute (Property) information is finished material (Material) automatically by the command functions button, the establishment of attribute (Property).The title of attribute and the title of group are consistent.And guide the user to finish this feature operation by interactive interface.

Fig. 2 is that attribute applies function interface;
Fig. 3 is a part parts attribute exploded view.
Embodiment
With reference to Fig. 1, this method is by computer-aided engineering technology secondary development environment, by TCL language and finite element simulation analysis software bottom technology, above-mentioned functions is integrated in the simulation analysis environment, realize the automatic identification of attribute and apply that the specific implementation step is as follows.
The first step: create the car body three-dimensional model
Second step: create the finite element simulation analytical model
The 3rd step: assembly that need to select definition material/attribute
(::ALTAIR::CRC::Update_MatProp::SelectComps)
The 4th step: create property file
According to the configuration file definition, determine the material/attribute information of assembly in the 3rd step; Create the CSV property file.
The 5th step: transfer the property operations interface
For applying attribute information, transfer the property operations interface.
The 6th step: transfer property file
Under the property operations interface, transfer the property file in the 4th step.
The 7th step: apply attribute
More new material/attribute information mainly comprises the assembly of choosing in the 3rd step is handled one by one, according to material and its corresponding attribute of thickness establishment/renewal, is not updated as assembly, creates attribute again.
With reference to Fig. 2, Config File-orders by Browse, reads in the CSV Mode B OM table that the user provides, and reads in by Import.The BOM table is the CSV form, and the inside comprises three row, and first classifies ComponentName as, and second classifies corresponding material Material as, and the 3rd classifies corresponding thickness information as;
Material File-orders by Browse, reads in the material depot file, comprises required material parameter in this material depot file, reads in by Import;
Select Comp-selects to upgrade the group of operation, and selected object will be presented in the Component Name form;
Component Name-has listed the component name that chooses at this;
Material-is the pairing title material of Component, and these title materials obtain by ConfigFile, and the component name that chooses embodies in Config File to some extent;
Update Mat/Prop-according to corresponding relation listed in the form, composes material to corresponding group in current model, and sets up corresponding attribute information.
The test example
With reference to Fig. 3, the present invention adopts the automatic applying method of attribute that certain body construction simulation analysis model has been carried out attribute and defines automatically.These body construction parts are 236, create Material File respectively, and apply the interface by automatic attribute and be input in the model, select the Component Name of 236 parts correspondences, by Update Mat/Prop function knob, attribute is applied on 236 parts automatically.
