HyperWorks composite material is emulated optimize technology and application

Composite material compares the intensity, amount that compare a pattern with its tall, anti-corrosive, fight the advantage such as exhaustion, more and more application received in industrial group. Be in especially aerospace respect, because iron and steel and coloured alloy are satisfied very hard slashing with each passing day weight, mechanical wait for design function demand, composite material was to receive wide application more. The 787 composite material dosage with A350 plane exceed Boeing 50% , also face a lot of major challenges in process of research and development at the same time, besides many galley proof with the ministry paragraph experiment the experiment checks, emulate optimizing a technology also is to solve all sorts of technology difficult problem, shorten the main technique measure of cycle of research and development. Altair company is developer of the world's banner engineering design technology, software of flagship product HyperWorks contained the famous module such as HyperMesh, OptiStruct, RADIOSS, MotionView, HyperStudy, it is the whole world solution of banner innovation of company level product. Go 10 years, altair company throws huge manpower material resources, cooperate cheek by jowl with aviation industry group, be based on HyperWorks software platform, developed composite material to build a model, emulate, optimize, the technology such as visible aftertreatment, had waited for a company to receive a large number of application in empty guest and Boeing at present. Composite material builds modular technology HyperMesh is the famousest CAE pre-treatment software on eye preexistence bound, offerred the unapproachable function that build a model and the most extensive CAD and CAE software port. Be aimed at composite material, hyperMesh offerred HyperLaminate of professional module of composite material pre-treatment, have intuitionistic and convenient user interface (like the graph 1 is shown) , can apace undertakes founding to composite material model, examination and editor, intuitionistic definition the ply of each lay up, angle and material attribute (fiber and matrix) , define criterion of all sorts of composite material invalidation to wait. HyperMesh supports the composite material lay up of Ply+stack to define way, the scope that defines a lay up of physics of each composite material namely (express with unit collect) , lay up of a physics is corresponding card of a Ply, rise each Ply by order cascade through Stack card next, form complete layer plywood. For example, composite material T long joist and structure of envelope adhesive bonding can pass the method that the graph shows 2 times to define. Use Ply+stack to build modular technology, can undertake building to plywood of composite material layer conveniently model and editor, three-dimensional show with lay up direction shows etc, if pursue,3 are shown. Composite material analyses HyperLaminate of the technology that seek solution to take classic layer plywood theory to seek solution oneself implement, can calculate those who give a plywood [A][B][D] matrix (show 4 times like the graph) , and equivalent material [G1] , [G2] , [G3] , [G4] matrix, can will complex three-dimensional the equivalent of plywood of composite material layer of each opposite sex is changed into simple 2 dimension anisotropy material flat, implementation model information is confidential, convenient use PSHELL unit to build a model. NextpageRADIOSS is a function powerful finite yuan seek solution implement, have linear, type of explicit, concealed is nonlinear the function that seek solution, have the algorithm such as Lagrange, Ou La, ALE, SPH, reach finite yuan, the numerical value such as limited volume handles a technology; The linear that can be used at the structure, nonlinear seek solution with what sort the problem such as solid coupling. The definition of RADIOSS support composite material and seek solution, supportive PCOMP defines lay up, PCOMPG definition is overall and statified, PCOMPP defines lay up appearance and order, can beg solution to give the stress of each lay up, meet an emergency and invalidation index conveniently. In addition, RADIOSS offers a variety of unit and material form, accurately imitate all sorts of nonlinear phenomenon, be like statified, invalidation, bump destroy etc, if the graph is shown 5 times; Provide comprehensive invalidation standard, be like criterion of Tsai-Wu, Chang-Chang, Hashin, Puck, Yamada Sun&Ladeveze-Allix, and can be in a kind of material apply a variety of invalidation standard. Composite material structure is optimized and decrease heavy technology " to reduce each gram weight effort " the working tenet that is engineer of every aircraft design. Composite material photograph compares a metal, have the advantage with light weight inherently, if fill those who distribute play composite material to be able to design function, undertake optimizing designing on lay up level, have more light quantified advantage. OptiStruct has powerful and comprehensive composite material to optimize ability, support from type of first spare parts structure, cut out to lay up appearance and ply distributing, to lay up angle and number of plies (lay up is compared) optimize, of each phase that fold order to layer of final lay up optimize design method, the stress that can consider each lay up, meet an emergency, invalidation, inflectional wait for function tie, and all sorts of craft requirements, offerred unprecedented composite material to optimize design ability, if the graph is shown 6 times,its design circuit. Composite material of applied case HyperWorks is emulated optimize a technology to had gotten applied extensively in group of global aviation industry, obtain many project positive result, partial case is shown 9 times like graph 7~ graph. It is already special and mature to composite material of last word HyperWorks is emulated and optimize a technology, be in abroad new generation plane (like A350 and Boeing 787) test and verify gets in design of research and development, the composite material project that consults a group to be the same as domestic unit in the aerospace project of Altair China also obtains a lot of project positive result in collaboration.
