The fast model face that is based on CAE analysis designs a technology

The modular face that uses strike out form to emulate software Autoform place to have designs a function, through analysing CAE computational result adjusts craft to design quickly, realized CAD/CAE to not have seam join, make qualitative thinking means OK come true quickly through quantifying a method, raised the dependability of technology program greatly, rose to design the engineer's work efficiency. The ceaseless development that drafts a technology as digital model is mature, CAE got developing quickly in domain of strike out form and the trend is economic change, make the powerful tool that craft analyses. In car mould industry, CAE technology is used at the car to enclothe a mould design, can make time trying a model reduces 50% above, economic benefits is very considerable. The car covers a measure bigger, panel surface quality asks outside taller, inside panel appearance feature is more complex, figuration difficulty is great, accordingly, traditional craft plan is custom-built it is to rely on the experience of technologist to decide, have the aid of completes modular face design at CAD system, and the craft analysis measure that CAD system provides is narrow, cannot the actor bad of program of technology of test and verify, more cannot craft of test and verify is additional rationality. Inchoate CAE technology applies at the mould designs a domain, its action is a kind of method that serves as pair of technology program to undertake test and verify merely. Emulate a result according to CAE, technologist needs to be aimed at the blemish that exists possibly to amend craft plan in CAD system, change modular face design, refer in CAE system to undertake imitate again next, till qualification till. This process makes the job periodic lengthen, can design personnel and analytic personnel to the communication between understands a reason and be brought about because of modular face sometimes make mistake, work efficiency also is reduced greatly, the advantage of CAE technology cannot be developed completely. Now, of CAD/CAE system without seam compositive implementation craft is additional complete parameter changes a design, the fast test and verify that also implemented craft plan and revise, it is the objective that broad technologist pursues all the time, also be a few relevant software business is some closer year of way that studies development. Current, the commercial CAE software that already had a few maturity realized this one function, autoform software is among them one outstanding. Applied Autoform can realize craft complement to design quickly, its are complete the handy sex that parameter turned design function to assure to revise, the curved surface quality that its generate is high, can export CAD system with a variety of formats, curved surface property supports CAM treatment completely. This kind is not had seam compositive also make the bounds between CAD system and CAE system increasingly ambiguous, technologist is OK and dedicated at perfecting technology program, and need not cave in at be in the modular face with CAD trival system is designed with modification job in, "Two hours of projects " , " Cheng of half Nature's engineering " already also became reality. Autoform software is to be in at present the software of CAE of figuration of a plank with domestic and international wider application, its are main module includes analyse of one footwork, method of addition, automatic reseau design of face of cent, model, optimize design, long foul line to spread out optimize etc, among them modular face designs what module implemented CAD/CAE system to not have seam compositive. The whole process that uses Autoform software to be able to realize to analyse technology program to decide from process (graph 1) . Modular face design basically includes to press makings face design and craft complement design, its design is reasonable it is to decide to pull extend process whether successful figuration and the key that acquire final and eligible product. Successful modular face design can make sure preform is not corrugate in figuration process, not burst, improvement makes a mechanical requirement when figuration, make material is out of shape everywhere agree equably, the craft such as the long edge of the foreword after the fixed position when convenient figuration is reached, flange. Controlling makings aspect is to point to the curved surface part beyond radius of sunken model round horn, below most circumstance, this curved surface should be the hyperboloid with planar, cylinder, cone or very small curvature to wait can exhibit curved surface, the appearance that controls makings aspect often not complex, but its are very big however to the influence of figuration result. Craft complement is to point to interpose at making with control the curved surface share between makings face, for precaution burst is mixed corrugate, make material flows equably to agree, often be in craft is additional model some of processing is made on face figure, accordingly, craft is additional figure is average more complex. Nextpage controls the liquidity that data basically considers when makings face is designed, also need to consider craft is additional at the same time design, commonly Guang Shunke exhibits control makings aspect. In Autoform, to making after undertaking punch direction reachs hole fill and attrib border light to arrange certainly, can undertake pressing expecting the face is designed. Autoform can be made according to the product appearance will be generated automatically control makings aspect, also offerred method of a few editors to edit adjust the figure that controls makings aspect. Autoform is generated automatically when controlling makings aspect, basically depend on press makings face to be apart from make a distance, control makings aspect advocate direction is controlled and control the aspect such as control of makings face figure. Face of ● pressing makings is apart from make the distance is to show expectant technology is complementary height. Control the upper part of makings face to assure to make an all parts be in, autoform can offer automatically to be apart from those who make a distance the least value. After pressing makings look unfamiliar to become, autoform can offer theoretic most contact the position first pull delay deepness. ● control controls makings aspect advocate the airspace that direction can control makings aspect certainly puts directional position, can decide automatically through Autoform, also can choose 0 ° , 90 ° or input value of one aleatoric angle will decide. The appearance control of face of ● pressing makings can pass control pressing to expect attrib border gradient is the biggest the greatest poor value comes to included angle and included angle of each place gradient implementation, still can be controlled through add or compiling reference point. If be flexible,control, that is to show the amount that makes the batten curve that controls makings aspect through control will control the appearance that controls makings aspect. Rely on what Autoform generates automatically to control makings aspect, can not reach the expectation that designs staff occasionally, right now, still need to reach editor feature control line to adjust through adding control makings aspect to expectation appearance. Graph 2 control makings aspect when showed through adjusting a few features control line is generated. Craft is additional the problem of a heat that parameter changes control to generate ever was academic research, current, this method already hasten is mature. Be opposite in Autoform craft is additional parameter turns control basically is to pass the parameter of pair of sectional lines to change control to come true, making through be opposite with pressure different position is sectional between makings face the control of line parameter, can generate a complete sophisticated technology complement. Graph 3 it is a complete craft sketch map of parameter of compensatory and sectional line, graph 4 it is a technology that uses parameter to change sectional line definition to generate compensatory example. Founding after pressing makings face and craft complement, can undertake CAE emulates computation. Use a tectonic modular face, the different share that can define a mould respectively (punch, sunken model and the circle that approach a limit) , had set all sorts of attrib border requirements (if press edge force, coefficient of friction and makings thick etc) , pull the equivalent that delays muscle to be able to be offerred with Autoform to pull the model that delay muscle. Pass computational result, the engineer can discover the flaw of the technology program of a design, also can be directly in Autoform undertake modification to pressing makings face and craft complement and undertake imitate analyses test and verify again, till get sound optimization program. The design of face of makings of Autoform middling pressure and craft complement part, changing undertake on reseau model, but this kind of design is the design that is based on geometrical model completely actually, is not the design that is based on reseau model, the curved surface that its found exports CAD system thoroughly in, the precision that controls makings aspect can reach level of class A curved surface even. The fast model face that parameter changes designed a technology to abound the design method of punch technologist greatly. Technologist is in initiative when have only commonly to modular face design roughly idea, parameter changes a design to make this kind of qualitative train of thought OK will come true through quantified method. The likelihood after application emulates test and verify needs to expect to pressing face or craft complement undertake modification partly, parameter changes control to also make this kind of long change goes to the lavatory so that mix very easily. The modular face design that undertakes on CAE analysis foundation makes the successful sex of technology program becomes can accuse, can raise a mould to try a model to be led successfully greatly, shorten the mould makes cycle.
