Abstract

The invention discloses a method for establishing an aviation brake fastener library based on a CATIA. The method comprises the following steps: classifying aviation brake fastener standard parts according to bolts, screws, screw nuts, gaskets, pivots and pins; establishing a standard part library; performing parametric modeling. By adopting the method, MBD definition of aviation brake fasteners is completed in CATIA, a fastener database is established by using a Catalog tool, the part library management is implemented by using electronic tables, digital model basis is provided for research of aviation brake products and development of serial products, repeated design working is reduced, and the working efficiency is improved.

Description

The method for building up in securing member storehouse is braked in a kind of aviation based on CATIA

Technical field

The invention belongs to parametric modeling field, particularly relate to a kind of aviation based on CATIA and brake the method for building up in securing member storehouse.

Background technology

In engineering goods, the part having 30%-70% is standard component or non-standard Common parts, these designs of part are similar but size different, and in product design and development process, the standardization of parts, seriation, generalization become the effective way improving Product Design Quality, shortening product development cycle.Therefore extensive use standard component, namely developing standard parts library can offer convenience for product design.In the design and manufacture process of aviation brake structure, the kind of standard component is very many, and wherein the usage quantity of threaded fastener accounts for the 30% ~ 40% of total part.Therefore reasonably apply standard component, especially threaded fastener in the design process, it is possible to simplify structural design, improve efficiency of assembling, shortening product design manufacturing cycle, reduction production cost, raising product quality are all had highly important Technological Economy meaning.

In recent years, since the nineties in 20th century, digitizing technique, in whole world manufacturing enterprise, is increasingly paid attention to particularly in the status in large aircraft manufacturing enterprise, and can oneself through becoming an important symbol that defeat par enterprise.Digitized development be one from inside to outside, by the old change to the new brand-new mode of production, it promotes the radical change of management system, organizational framework, standard criterion, method for designing, production running, mode of thinking and working method.

MBD technology is the new trend of cad technique development, and oneself through being applied in airplane design manufacture.The requirement that manufactures and designs of aircraft uses three-dimensional entity model as the unique foundation in manufacturing process, and after adopting MBD model, threedimensional model will pass through the links produced in design, frock, technique, manufacture and assembling etc..But having numerous parts structurally to have similarity, so need to do the work of repetition when setting up MBD model, this will waste the substantial amounts of time, reduce the efficiency of exploitation, extend the construction cycle of new product.

Summary of the invention

It is an object of the invention to provide a kind of aviation based on CATIA and brake the method for building up in securing member storehouse, it is intended to reduce design iterations work, improve work efficiency.

The present invention is achieved in that a kind of method for building up based on the aviation braking securing member storehouse of CATIA includes:

Step one, by aviation braking fastening standard component classify according to bolt, screw, nut, packing ring, rivet, pin；

Step 2, establishment Standard partslibrary；

Step 3, parametric modeling.

Further, the described concrete steps creating java standard library include:

Step one, data prepare；

Step 2, part analysis；

Step 3, definition design variable；

Step 4, set up mathematic(al) representation；

Step 5, set up parameterized model；

Step 5, associated design table；

Step 6, inspection model；

Step 7, MBD define；

Step 8, establishment Catalog file.

Further, described parametric modeling method particularly includes:

The data relevant with model are left in table form in corresponding file, utilize DesignTable design table instrument the parameter of model to be associated with the data in form, design in table instrument by selecting different data to realize the driving to model at DesignTable.

The present invention completes the MBD definition of aviation braking securing member in CATIA, Catalog instrument is used to create securing member data base, electrical form is used to carry out the management of parts library, mathematical model basis is provided for the development of aviation Brake Products and the exploitation of tandem product, decrease design iterations work, improve work efficiency.

Accompanying drawing explanation

Fig. 2 is the establishment java standard library flow chart based on CATIA that the embodiment of the present invention provides.

Detailed description of the invention

For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and it is as follows to coordinate accompanying drawing to describe in detail.

Refer to Fig. 1 and Fig. 2:

The method for building up in securing member storehouse is braked in a kind of aviation based on CATIA, including:

S101, by aviation braking fastening standard component classify according to bolt, screw, nut, packing ring, rivet, pin；

S102, establishment Standard partslibrary；

S103, parametric modeling.

Further, the described concrete steps creating java standard library include:

Step one, data prepare；

Step 2, part analysis；

Step 3, definition design variable；

Step 4, set up mathematic(al) representation；

Step 5, set up parameterized model；

Step 5, associated design table；

Step 6, inspection model；

Step 7, MBD define；

Step 8, establishment Catalog file.

Further, described parametric modeling method particularly includes:

For button-headed bolt, first in " formula ", set up the characteristic parameter determining bolt shape, then set up the threedimensional model template of button-headed bolt, and with characteristic parameter, its sketch is carried out Complete Bind, " design table " function is finally utilized to add the parameter list previously put in order, it is made to be associated with model, it is achieved the seriation of part.

Newly-built " Catalog " file in CATIA, the model file having built up is selected by " adding part series ", consider later stage assembling process is likely to temporarily will not use the dimension information of part, therefore mark collection information is temporarily hidden after having defined by MBD, when calling as needed the dimension information of part can show mark collection information in model tree.

In carrying out trim designs process, ordered by " directory browser " in the Tools menu, dialog box is opened the HBStandards parts library file built up, the part in parts library can be browsed at directory browser window.Figure directory listing is chosen the part of dimension, double-clicks the part that can generate correspondence, and join in current assembly.

The above is only to presently preferred embodiments of the present invention, not the present invention is done any pro forma restriction, every technical spirit according to the present invention, to any simple modification made for any of the above embodiments, equivalent variations and modification, belongs in the scope of technical solution of the present invention.
