Abstract
Cilj ovog rada je provedba analize naprezanja i deformacija aksijalnog kompenzatora s nepomičnom prirubnicom, te analize puzanja materijala na povišenoj temperaturi. Rad je podijeljen na osam poglavlja, koja u cjelini zaokružuju tematiku rada sa praktičnog i teorijskog aspekta. Prvo poglavlje je uvodno, te se njime nastoji načeti tematika koja se prožima kroz rad. U drugom poglavlju opisana je uloga i podjela kompenzatora, s naglaskom na aksijalni kompenzator, te je prikazana geometrija i karakteristike modela aksijalnog kompenzatora konstruiranog u software-u SolidWorks. Trede poglavlje se bavi teorijskim pojmovima mehanike čvrstog tijela, s ulogom boljeg razumijevanja problematike modela, a opisane su i najznačajnije teorije čvrstode, kojima se pokušava previdjeti pojava trajnih deformacija. Četvrtim poglavljem je opisan proces, te mehanizmi puzanja materijala, kao posebnog oblika nastajanja trajnih deformacija. U petom poglavlju je predstavljena metoda konačnih elemenata, koja se primjenjuje u software-u Femap, u kojem su modelirane analize kompenzatora. Šesto poglavlje opisuje postupak pripreme i provedbe numeričke analize naprezanja i deformacija. Priprema analize uključuje definiranje geometrije, svojstava materijala, umrežavanje modela, definiranje kontakta kliznih cijevi, te postavljanje oslonaca i opteredenja. Nakon toga su provedene tri različite statičke analize, kojima je modelirano ponašanja aksijalnog kompenzatora. U sedmom poglavlju prikazuje se postupak i rezultati analize puzanja. Kako se radi o nelinearnoj analizi, model se priprema na svojstven način. Opisane su postavke analize i kontakt definiran slide line elementima, te koeficijenti Nortonovog zakona puzanja materijala. Za kraj su uspoređeni analitički i numerički rezultati procesa puzanja materijala. Osmim poglavljem zaključuje se tema i rezultati ovoga rada.
Abstract (english)
The aim of this paper is to analyze stress and strain characteristics of the axial bellow with a fixed flange, and to analayze creep of material at high temperature. The paper is divided into eight chapters, which round off the theme of practical and theoretical aspects. The first chapter is an introduction, and it only scratches the surface of the main theme. The second chapter describes each type of bellow and their applications. As the assignment of this paper is modeling of the axial bellow, in this chapter geometry and characteristics of the axial bellow (modeled in SolidWorks) are shown. The third chapter deals with theoretical concepts of solid body mechanics and the most significant strength theories, which attempts to overlook the occurrence of plastic deformations. The fourth chapter describes the creep mechanisms as a special way of forming a plastic deformation. In the fifth chapter, the finite element method is presented, which is applied in the Femap software, in which bellow analysis is modeled. Chapter six describes the process of preparation and implementation of numerical stress and strain analysis. Preparation of the analysis involves defining geometry, material properties, meshing, defining the contact of two inner liners, and setting the supports and loads. Three different static analysis were performed, modeling the behavior of the axial bellow. The seventh chapter shows the procedure and results of the creep analysis. As for nonlinear analysis, the model is prepared in a different way. The analysis properties, contact defined by slide line elements, and the Norton Creep law coefficients are described. In the end, the analytical and numerical results of the creep analysis are compared. The eighth chapter concludes the theme of this paper.
