VIRTUAL PROTORYPING Virtual prototypig is a egieerig disciplie based o a software able to shape a mechaical system, simulate ad visualize i a 3D format its behavior, based o real fuctioig coditios, optimizatio of the desig by iterative studies.

3 Aalele Uiversităţii Costati Brâcuşi di Târgu Jiu, Seria Igierie, Nr. /011.OPTIMIZAREA PROTOTIPULUI Optimizarea prototipului virtual se face parcurgâd următoarele etape: parametrizarea modelului; defiirea variabilelor de proiectare; defiirea fucţiilor obiectiv petru optimizare şi a costrâgerilor de proiectare; elaborarea studiilor de proiectare şi a experimetelor; optimizarea modelului pe baza pricipalelor variabile de proiectare. Parametrizarea modelului simplifică modificarea acestuia, deoarece ajută la redimesioarea şi repoziţioarea automată a compoetelor. Variabilele de proiectare permit crearea parametrilor idepedeţi şi modelarea cuplelor ditre obiecte. Studiul de proiectare descrie capacitatea de a selecta o variabilă de proiectare, care mătură o gamă de valori şi apoi simularea comportametului diferitelor modele obţiute, î scopul de a îţelege sesibilitatea sistemului global la aceste variaţii ale proiectului. Fucţia obiectiv este o cuatificare umerică care face disticţia ître proiectele cadidate. Costrâgerile sut limite care, direct sau idirect, elimiă proiectele iacceptabile; acestea ia adesea forma uor obiective suplimetare î proiectarea mecaismului. Î geeral, problema de optimizare este descrisă ca o problemă de miimizare sau maximizare a fucţiei obiectiv cu variabile de proiectare selectate, î timp ce satisface diverse costrâgeri ale proiectului. Ca parte a procesului de proiectare, optimizarea maipulează ecuoscutele (variabilele) ditru proiect petru a ajuge la u proiect bu, care îdeplieşte toate scopurile (obiectivele) şi restricţiile (costrâgerile). Dacă aceste caracteristici pot fi cuatificate, tehicile de optimizare pot fi folosite petru a ajuge aalitic la cea mai buă soluţie teoretică..prototype OPTIMIZATION Virtual prototype optimizatio ca be realised by passig through the followig stages; defiig desig variables; defiitio of the objective fuctios for optimizatio ad desig costraits; issuig desig studies ad experimets; optimizatio of the patter based o mai desigig variables. Patter parameterizatio simplifies its modificatio, as it helps at automatic redimesioig ad repositioig of compoets. Desig variables allow creatig idepedet parameters creatio ad shapig couples from objects. The desig study describes the capacity to select a desig variable, sweepig large scales of values ad afterwards simulatio of the behavior for differet obtaied patters, with the purpose to uderstad the sesibility of the global system for these variatios of the project. The objective fuctio is a umerical quatificatio makig the differece betwee cadidate projects. Costraits are limits which, directly or idirectly, elimiate iacceptable projects; these take the form of some supplemetary objectives i the desig of the mechaism. Geerally, the optimizatio problem is described as a problem for miimizig or maximizig the objective fuctio with selected desig variables, meawhile satisfyig differet costraits of the projects. As part of the desig process, optimizatio maipulates ukow objects (variables) from a project to reach a better project, accomplishig all purposes (objectives) ad restrictios (costraits). I case these characteristics ca be quatified, the optimizatio techiques ca be used to aalytically reach a better theoretical solutio. 3.PLATFORMA SOFTWARE COMPLEXĂ PENTRU TESTARE ÎN MEDIU VIRTUAL Î cotiuarea lucrării este prezetată o platformă software complexă [] petru 3.COMPLEX SOFTWARE PLATFORM FOR TESTING IN A VIRTUAL ENVIRONMENT As cotiues, i this paper is preseted Aals of the Costati Brâcuşi Uiversityof Târgu-Jiu,Egieerig Series, Issue /011 91
