Abstract
U diplomskom radu definirani su osnovni zakoni i odredbe koji se tiču opreme pod tlakom. Također će biti riječi o osnovnim informacijama o pojedinim metodama bez razaranja, njihovim prednostima, nedsotacima, principu rada i primjeni. Glavno težište ovog rada je metoda ispitivanja akustičnom emisijom koja se pokazala jedna od boljih medoda ispitivanja konstrukcija različitih oblika, dimenzija i sastava materijala. Ispitivanje je provedeno na terenu na posudi pod tlakom oznake prema DIN normi StE470. Volumen posude je 2,7 m3 s najvećim radnim tlakom od 16,4 bar i radnog medija UNP. Prilikom ispitivanja koristilo se dva piezoelektrična senzora s ugrađenim pojačivačima signala. Posuda pod tlakom je bila opterećena s 6 bar, 9 bar i 12 bar što je njezin najveći radni tlak u posljednjih 12 mjeseci. Temperatura okoliša je 20 °C, a posuda pod tlakom za vrijeme ispitivanja iznosi 50 % vlastitog ukupnog volumena kapljevine. Rezultati ispitivanja omogućuju određivanje razine opasnosti medija koji se nalazi u posudi pod tlakom, aktivnosti praćenja AE, pojava Kaiserova ili Felcity efekta koji ujedno znači i kraj radnog vijeka posude pod tlakom. Također će biti provedena i numerička analiza posude pod tlakom za linearno elastičani materijal i linearno elastičani – idealno plastičani materijal. Uvjeti kojima su podvrgnuti 3D modeli za dva različita materijala posude pod tlakom su tlak od 16,4 bar narinut na unutarnje stijenke posude i četiri fiksna oslonca. Prilikom analize koristili su se tetraedarski konačni elementi.
Abstract (english)
This paper reviews basic principals and orders of non destructive testing methods for pressure vessel. Also there will be information about non destructive testing methods, theirs advantages and disadvantages, work principals and use. The main point of this work will be on acoustic emission testing which is one of the better methods for non destructive techniques for testing materials different shapes, dimensions and structures. Testing was terrain on a material of pressure vessel on DIN norm StE470. Volume of pressure vessel is 2,7 m3, the highest pressure was 16,4 bar with liquefied petroleum gas (LPG). There was two piezoelectric sensors during the testing. Pressure vessel was loaded with 6 bar, 9 bar and 12 bar which is the higher work pressure in the last twelve months. During the testing the temperature was 20 °C and pressure vessel was on 50 % of owerall volume of petroleum gas. The results will show how to determine level of danger of the media, activity AE, Kaiser and Felicity effects which means end of use of pressure vessel. There will be also made numerical analysis of pressure vessel for linear elastic materials and linear elastic-ideal plastic materials. In numerical analysis the 3D pressure vessel will be loaded for 16,4 bar on the inner side of pressure vessel with four fixed supports. During the analysis program was using tetrahedron finite element.
