Data of data of use Ansys Granta MI runs software, you can visit integrated and overall data, for example MaterialUniverse data set, contained the technology that faces data of thousands of kinds of project, economy and environmental information among them; Still have advanced Global Polymer library, included 100, the detailed information of a variety of 000 polymer brands (the polymer that includes to come from SABIC among them) .

SABIC is the petrochemical manufacturer with banner whole world, production applies at the high-powered polymer of car headlight. In the design technological process that waits for numerous project in car application, through using Granta and Ansys much physics field emulates a tool, the user can come true to choose without seamed material.

SABIC offers a series of material solutions, include among them high temperature resistant compound of the ULTEM colophony series of the solution, LNP and PC copolymer colophony, NORYL colophony. The user can obtain the data of these material in the material library in Granta MI Enterprise and Ansys Granta Selector not only, also can derive its easily all sorts of Ansys emulate platform.

The reason with deeply welcome colophony

ULTEM gets together ether acyl inferior amine (PEI) a variety of application that colophony is used extensively at each industry, include equipment of electron, car, medical treatment, industry and infrastructure. These colophony brands can note the geometrical figure that model shapes to need for place normally, realize industry to estimate the mass production of class thereby.

Headlight of digital matrix LED

The modelling design of car headlight is the substantial that car brand identifies. Although the new technology such as LED can be offerred high-powered and get used to illume oneself, but also brought new design challenge for manufacturer. These designs involve geometrical complexity of height and numerous component. LED and the high temperature that electronic component produces can affect geometrical figure, affect illume performance then. In use of lamp beam of light is OK before relevant car standard set strictly the distance of deviate, with avoiding to come head on the driver of the car causes blindfold.

Graph 1: SABIC rolled out all sorts of brand material solutions, include copolymer of colophony of ULTEM colophony, LNP compound, NORYL, LEXAN and EXTEM resin. The SABIC ULTEM that concentration showed here colophony

What the ULTEM colophony of SABIC can satisfy digital matrix headlight adequately is high temperature resistant the design asks (be as high as 230 ℃ ) . In addition, the dimension stability of this material and low commentate gas property can be rivalled with metal and vitreous material solution, but its weight is lighter. Application of potential headlight of digital matrix LED includes parts of an apparatus or appliance of small lens of microscope limb, spacer, bracket, illuminator and number (DMD) socket.

More intelligent design

In begin before actual production is made and checking, use number model comes function of test and verify and producibility already made standard of a kind of industry, such doing conduce to decrease redesign, ensure contented development time limit, achieve cost goal. Pass a visit high quality, complete and data of comparable many bits of data, engineer and design personnel can ensure the accuracy of fictitious test and verify, let them thereby can more confidence completes design technological process dye-in-the-woodly, reduce design mistake and follow-up product breakdown.

No less, method of much physics field favors by the engineer. Good news is, SABIC and Ansys collaboration are offerred about ULTEM resinous detailed material information, can use at main Ansys to seek solution directly implement. These data include stress - meet an emergency and creep curve nonlinear mechanical attribute, and the pyroelectricity data that changes along with temperature. The user can be mixed in Granta MI Granta Selector gets ULTEM data data in library of medium Global Polymer material, derive its Ansys emulates platform, include Ansys Workbench and Ansys Mechanical.

Car manufacturer is not the group that much physics field probes in wanting exclusively to be designed in optics. Last year, an undergraduate group used tool of field of Ansys much physics to design racing car of a solar energy, include to use Speos to develop headlight design. Use Speos, this group design went out to accord with contest regulation and the light with lower specific power consumption. This can raise engine to exert oneself not only, and still can reduce overheat problem significantly. Accordingly, more intelligent material chooses to conduce to the light that designs more cabinet, lower cost. Meanwhile, this group still uses Mechanical to begin structural analysis, use Ansys Fluent to undertake computational hydrokinetics (CFD) emulate.

5 paces go: 5 simple measure finish material to choose

Now, let us be with how choosing ULTEM colophony exemple, will explore Granta-SABIC work flow.

Emulate data data through combining use Granta (include SABIC polymer) and field of Ansys much physics emulates a tool, you can complete whole car headlight design.

Measure:

Be found from inside Granta material database and choose needs ULTEM colophony

Examine all available data, include to heat up an analysis

In deriving its the emulation that chooses to you applies. For example, design personnel often uses Workbench to emulate compositive platform, will solve the problem related structure and temperature with integrated Mechanical

The basis needs tool of field of compositive other much physics, for example emulation software of refrigeration of Ansys Icepak electron or design of Ansys Speos optics and software of test and verify

Appoint colophony the first selection material in be Granta MI

Graph 2: Appoint and save in Ansys Granta MI Enterprise Gateway recommend or the material of first selection

Profit from can be mixed from material of same platform choice establish a model, design personnel can realize high quality design, application is crossed to compare data in whole design technological process, choose first-rate material in order to ensure, raise the accuracy of fictitious test and verify.

For example, ULTEM colophony supports the Yan Ke products plan that needs large-scale treatment. All sorts of advantages such as the insulating properties that it has distinctive tall hear resistance, stability, high strenth, tall stiffness and dimension stability. This kind of colophony is to not have substantially haloid flame retardant, have at the same time infra-red (IR) sex of transparency, hydrolyze and chemical stability.

From only then to eventually material support

In the system that Granta MI Enterprise can embed industry precedes completely, include a CAD (CAD) , the computer assists a project (CAE) manage with product lifecycle (PLM) , in order to ensure accurate in designing circuit each applying data data and attribute.

In addition, no matter be to check data to still emulate software, granta can ensure data and result are complete but date from. Data is as related as emulation model photograph from beginning to end, this allows an user to feed the data in emulate and analytic history undertake tracking. Such, engineer and design personnel can enhance the degree of confidence of emulation result, thereby more convenient further analysis is begun in later period, the company intellectual property that in be emulation job, includes (IP) provide protection.
