20.500.12556/RUL-149163 Določitev napetostno-deformacijskega stanja tesnila po vgradnji v realno aplikacijo Determination of seal stress-strain condition after assembly in real application Cilj te naloge je s pomočjo tlačnega testa pridobiti materialne lastnosti silikonskega tesnila. S tem bomo ustvarili materialni model, ki ga lahko uporabljamo v nadaljnjih simulacijah tesnil iz tega materiala. Ker navadna kalibracijska orodja ne zagotavljajo ustreznih simulacijskih rezultatov, smo morali materialne parametre pridobiti preko obratnega inženiringa. Tlačni test smo simulirali v programskem orodju Ansys in s pomočjo programa za obratni inženiring optiSLang spreminjali materialne parametre hiperelastičnega materialnega modela, dokler v simulaciji nismo dobili rezultatov, ki so se ujemali z meritvijo. Pridobljene materialne konstante smo nato uporabili za simulacijo tesnila v realni aplikaciji. The objective of this assignment was to obtain the material properties of a silicone seal with the help of a pressure test. In this manner the parameters of a material model are obtained that can be used in further simulations of sealing elements made of this material. Since ordinary calibration tools do not provide adequate simulation results, the material parameters need to be obtained through reverse engineering. The pressure test was simulated in the Ansys software tool and the material parameters of the hyperelastic material model were varied using the reverse engineering program optiSLang until we obtained the results in the simulation that matched the measurement. The obtained material constants were then applied to simulate the sealing element in a real application. tesnila obratni inženiring metoda končnih elementov hiperelastičnost tlačni test optiSLang sealing elements reverse engineering finite element method hyperelasticity compression test optiSLang true false false [M.
