dc.description.abstractThe paper deals with measurement and mathematical simulation of expansion of a hydraulic hose including the effect of oil bulk modulus. Young’s modulus of elasticity of the hydraulic hose is experimentally determined by expansion method and by compression method. The modulus of elasticity of the hydraulic hose obtained from the expansion method is determined by measurement of an oil volumetric gain, which is compressed inside the investigated hose after the oil expansion. The Young’s modulus of elasticity of the hydraulic hose obtained from the compression method is determined by measurement of oil flow and pressure increase vs. time in the hydraulic hose. The oil bulk modulus is experimentally determined by means of the expansion method and the method of oil compression in a steel pipe. A hydraulic circuit for simulation of the oil expansion from the hose and the steel pipe was created using Matlab SimHydraulics software. The oil volume increase after the expansion from the hydraulic hose and the steel pipe was numerically simulated. Furthermore, time dependencies of pressure decreases during the oil expansion from the hydraulic hose and the steel pipe were numerically simulated. Results of the mathematical simulations were compared with the experiment while using the Young’s modulus of elasticity of the hose and the oil bulk modulus that were determined by the expansion method and by the compression method.cs

dc.description.abstract-enRad se bavi mjerenjem i matematičkom simulacijom širenja hidrauličnog crijeva, uključujući učinak modula stlačivosti ulja. Youngov modul elastičnosti hidrauličnog crijeva eksperimentalno je određen metodom ekspanzije i metodom kompresije. Modul elastičnosti hidrauličnog crijeva dobiven metodom ekspanzije određen je mjerenjem povećanja volumena ulja, sabijenog u ispitivanom crijevu nakon ekspanzije. Youngov modul elastičnosti hidrauličnog crijeva, dobiven metodom kompresije, određen je mjerenjem protoka ulja i porasta tlaka u hidrauličnom crijevu u odnosu na vrijeme. Modul stlačivosti ulja eksperimentalno je određen metodom ekspanzije i metodom kompresije ulja u čeličnoj cijevi. Hidraulični krug za simulaciju širenja ulja u crijevu i čeličnoj cijevi stvoren je primjenom softvera Matlab SimHydraulics. Povećanje volumena ulja nakon širenja u hidrauličnom crijevu i čeličnoj cijevi numerički je simulirano. Nadalje, vremenske ovisnosti smanjenja tlaka tijekom širenja ulja u hidrauličnom crijevu i čeličnoj cijevi numerički su simulirane. Rezultati matematičkih simulacija uspoređeni su s eksperimentalnim tijekom primjene Youngova modula elastičnosti crijeva i modula stlačivosti ulja određenih metodom ekspanzije i metodom kompresije.cs
