French ESI group has composite material design, craft to emulate, the series that mechanical function analyses emulates value catenary solution, include PAM-QUIKFORM, PAM-FORM, PAMRTM, PAM-AUTOCLAVE, SYSPLY and PAM-CRASH. Among them, PAM-QUIKFORM is tool of lay up design, PAM-FORM and PAM-RTM and PAM-AUTOCLAVE are craft emulation tool, and SYSPLY and PAMCRASH are tool of mechanical function analysis. These solutions are having wide application in composite material domain. PAM-QUIKFORM of design of composite material lay up is OK imitate enhances body to be out of shape in the fiber in laid process, apply to spin to enhance the body, cloth that do not have abb (UD) or without inflectional fabric (NCF) . Strengthen put oneself in another's position to spin, PAM-QUIKFORM uses the lay up algorithm of the standard in industry. In addition, QUIKFORM includes the particular UD inside a course of study to enhance algorithm of body lay up, this algorithm is OK imitate fibrous distributings, and lay up algorithm of the standard is general and unwell with hereat kind problem. The computation of PAM-QUIKFORM from be begun by the reseau of laid spare parts, can obtain fibrous trend and plane to develop a plan. Dot of spare parts reseau, contact and fiber direction are the data-in of PAM-QUIKFORM model, and output data includes staple trend, cut horn and plane of composite material spare parts to develop a plan. PAM-QUIKFORM is completely compositive in PAM-RTM and SYSPLY, can provide the information such as lay up direction for SYSPLY, offer the parameter such as hole rate and permeability for PAM-RTM. PAM-QUIKFORM emulation software can forecast composite material fiber to enhance body to shape the process is out of shape mediumly. Be based on geometrical map algorithm, it can be planted in a few seconds inside the material that is informed a choice shapes in the component can appear in the process corrugate wait for potential problem. In the meantime, emulation result still can give out the plane of plank lay up develops a plan, can mix for platoon appearance next makings provide reference. QUIKFORM can be out of shape without abb cloth fibrous in imitate laid process, this is unique functional character in congener product in the market. Its capture algorithmic mechanism can be informed laid of the cloth that do not have abb appear in the process be out of shape in detail mechanism, for example slip, fiber spreads between the layer etc. Pressure of composite material, plastic sheet and heat shape imitate PAM-FORM shapes as metalloid sheet imitate major software, be what one kind develops by PAM-STAMP and come is explicit and finite yuan of software, can fiber of imitate composite material is in shape the new orientaton in the process, can use those who wait at folding a composite material, plastic sheet, fabric, carpet to shape. PAM-FORM applicable shapes at blowing air, diaphragmatic shape, drawing shapes, contain tigidity and flexible the extrusion of the tool, thermoplastic wait for a process with treatment of hot solid polymer. Its representative application includes blanket and fabric to shape, car interior is plastic with fabric face plate, the car lights material or blank bin, shock absorber, dashboard, plastic container, food is packed, advanced spaceflight and car fiber enhance a component to wait. Shape as software, PAM-FORM can be used at the definition and optimize craft condition, it solved following problem: Whether shape with some kind of material a certain component and do not appear rupture, corrugate or other any blemish? Be economic data and reduce waste as far as possible, ought to use He Chongchu only then appearance? Should use why to plant means combining a model? Choose how old concussion speed and pressure? Synthesize to the layer model, is this kind of order that fold a layer feasible? How to choose to shape temperature and mould temperature? Regard a PAM as the product, PAM-FORM is the one part in the completely numeric solution that ESI company offers. For example: (1) use SYSPLY analyses composite material stress accurately, need gets ply and fiber direction information afresh after shape, and this information is provided by PAM-FORM. (2) analytic collision and concussion problem use PAM-CRASH. (3) RTM (colophony delivers moulding) when inject is analysed, can use shape from dry fiber final local ply and fiber direction reach permeate, and this result is offerred by PAM-FORM. (4) before heat shapes, use plastic sheet or layer board comes warm-up is fused and plastic, easy bring about the temperature on whole chip to distributing inhomogenous. Improvement shapes a of imitate result simple method undertakes imitate of a warm-up with SYSTUS namely, benefit regards PAM-FORM calculative as initiative temperature with calculative temperature. Aviation of available customer firm, Europe defends the typical client of PAM-FORM Wu spaceflight company (Hui Erpu company of the EADS) , aviation that amount to all alone, United States. Colophony is delivered drafting PAM-RTM with injection mould is the major of imitate of colophony injection process that is based on fiber aggrandizement software, use extensively at composite material and plastic industry, it is tall sex price compared imitate liquid state is compound shaping solution. PAM-RTM offerred the quick solution that devises beforehand, refine process and mould to optimize, final design examines computation, but imitate colophony is delivered shape (RTM) , vacuum assists RTM (VARTM) assist colophony infuse with vacuum (VARI) 3 kinds of craft. PAM-RTM can read in PAM-FORM to shape beforehand result, process of different resinous warm-up and fill mix imitate solidify. PAM-RTM is the package of three-dimensional simulation software that innovate and uses easily, include to optimize mould design and RTM process parameter. PAM-RTM optimizes the parameter that immediate impact pressure distributings, namely the inject pressure in mould fill process, discharge, shape temperature, closing force and inject opening position and position of platoon a place with a draught, return what can forecast the solidify inside the mould to evolve, can show to the circumstance of peak face flows inside modular antrum, conduce to avoid occurrence fill problem (if do a drop,wait) . NextpagePAM-RTM can provide following help to industrial user: Different inject strategy is evaluated before production mould; Examine front of the colophony inside antrum to do the fill question such as the dot with preventing occurrence such as; Optimize the position of inject dot and vent; OK and direct observation distributings in the pressure in the process that write a standard; Forecast the temperature change inside modular antrum; Imitate component colophony is sclerotic; Cast total cycle time; The analysis fills influence parameter of the model, pressure of viscosity of such as colophony, inject and inject rate; Content of analytic geometry dimension and appearance, fiber, enhance body and colophony attribute to change pair of shaping effects. PAM-RTM still offers very rich turn out to handle a function, process of the fill in can letting an user control consideration is different the trend of parameter, the degree of such as temperature, pressure and solidify. Inject imitate considered to shape beforehand simulative is out of shape result information (but direct from PAM-FORM, PAMQUIKFORM, system of design of component of the composite material that amount to all alone and FiberSim are inputted) . PAMRTM can imitate is different the colophony of the type, include annulus oxygen, polyester, vinyl ester, phenolic aldehyde is plastic wait. PAM-RTM basically passes a mould three-dimensional heat is conducted inside warm-up, mould, source, the control such as osculatory thermal resistance heats up a process. To fill and solidify, the user is OK oneself define viscosity and solidify function, consequently can imitate new colophony. Fill the solidify imitate after noting a process to reach to be based on Kamal Sourour model. Autoclave craft emulates autoclave craft only then at 20 centuries 40 time, from 20 centuries 60 time begin to be used extensively, it is the produce and develops development technology that is aimed at the 2nd acting composite material, producing envelope especially kind tremendous effect was produced when the spare parts, already made a kind of mature technology now. The composite material that produces by autoclave craft occupies the 50% above of crop of whole composite material, 80% above are as high as in aerospace domain proportion. Autoclave craft already was used in great quantities by manufacturers of each composite material component. According to investigation, all plane manufactories and relevant unit are using China this kind of craft, and almost all planes are designed and place of courtyard of technology scientific research also is studying this kind of technology is right the influence of intensity of spare parts structure. Solve autoclave existence problem or the means that use a test at present, expended many time and cost so, and still cannot make sure the test is successful. ESI group understands from inside each big aircraft manufacturer, craft of the autoclave in using a process actually still is put in a lot of problems, like craft parameter unreasonable, workpiece puts the position improper etc, these problems are perplexing broad user. According to autoclave craft characteristic, ESI group summons departmental door expert, form the development group of autoclave craft software, last a period of time emulates software PAM-AUTOCLAVE 2 years at rolling out autoclave craft eventually. This plan can be the craft parameter that improves autoclave technology and mould design to provide directional guidance, will improve manufacturing efficiency greatly, reduce manufacturing cost. Flow of computation of the need in autoclave craft, pressure, conduct heat, process of solidify, spring back, suit to use limited volume method. PAM-AUTOCLAVE is based on limited volume law just about, the flow inside the canister in analysing autoclave craft, pressure, conduct heat, the process such as solidify, spring back. Structure of composite material of professional and mechanical analysis evaluates composite material characteristicly the diversity that must want to consider data (include to enhance interlining of oxygen of annulus of polyester of plastic, glass, carbon, beehive or beehive core material, carbon - carbon composite material) and their primitive and mechanical function (inhomogenous sex. The comprehensive data database that SYSPLY offers brings huge advantage for definitions of all sorts of material of three-dimensional structure lay up, and its distinctive combination function undertakes be designinged quickly evaluate and study to bring very large competition dominant position for the engineer. SYSPLY can is opposite any overall and equivalent mechanical attribute that fold a layer in great quantities have alternant consideration, use stress / the design of the invalidation that fold a layer and component of composite material of dynamic and characteristic test and verify, it is design, analysis and the professional software that optimize composite material structure. SYSPLY has distinctive lay up editor, convenient material to character shows and be calculated function, professional aftertreatment function, make the design of composite material and analysis more convenient. The main function of SYSPLY is the statics that has composite material, kinetic reach general nonlinear the analysis of the problem. Concussion of composite material collision destroys mechanical emulation PAM-CRASH the diversity of character of structure of mature composite material, include groovy composite material (if enhance oxygen of annulus of polyester of plastic, glass, carbon) reach the composite material that place core (wait like composite material of interlining of material of core of interlining of beehive core material, bubble) , this compose relation and solution are the comprehensive data that it provides analysises of all sorts of collision of concussion of structure of three-dimensional composite material bring huge to facilitate. To colophony base composite material, PAM-CRASH uses theory of classical layer plywood to analyse the invalidation of composite material, phenomenon of the stress between the invalidation that basically analyses answer material composition, layer, delamination. PAM-CRASH can provide a variety of invalidation standard, applicable the be no longer in force that all sorts of composite material leave in different load situation, the configuration with main different consideration and material function bump to plane dropping suck can influence, still can consider the composite material that place core gooey intensity, analytic board and the delamination phenomenon that place core. The application of plan of ESI group composite material and progress in July 2006, ESI group and airbus company announce to undertake cooperative in fictitious production domain. Be based on the statement of the airbus, ESI group falls in CATIAV5 environment, to using liquid state answer the composite material of synthesis method makes the development that had fictitious application program, the airbus is in its are met in project of new-style and advanced aerostat large-scale use composite material. The time of fictitious emulation technology has exceeded the RTM of application of main shareholder EADS of the airbus 10 years, with the production that enhances colophony inject spare parts at imitate fiber. In the past a few years, EADSCCR improves the performance of PAMRTM with ESI group collaboration, make more the demand that gets used to new-style aerostat project. PAM-RTM For CATIA V5 is the result that PAM-RTM function applies at CATIA V5, this is ESI the associated project that two years with the airbus collaboration plans. This simulation software is not had directly with noumenon geometry in CATIA V5 environment seam compositive. This kind of completely compositive application reduced imitate cycle significantly, can let mould design and imitate result have direct correlation. It also makes an user direct undertake injecting analytic becoming a possibility on CAD model, what data of the geometry in assuring to be in what last repeatedly to improve a process flows is successional, can save time and cost greatly thereby. In January 2007, ESI group releases the PAM-QUIKFORM that is based on environment of CATIA 　 V5 formally. This development project is the CAA V5 Gold Software that ESI group and Dassault company sign the one part of cooperative agreement. This new product of ESI group can make the user uses CATIA 　 V5 better composite material design, information of composite material lay up is defined in CATIA, can undertake fiber shapes directly next analysis, this will improve manufacturing efficiency effectively.
