20.500.12556/RUL-95519 Zasnova hidravlične naprave katapulta Design of hydraulic device for catapult Hidravlični katapult predstavlja inovacijo v svetu adrenaliskih doživetij, ki so vse bolj priljubljena. Katapult deluje tako, da s konstrukcijsko roko pospeši po krožnici in v najvišji legi izstreli človeka v vodo. Pri tem pa moramo paziti, da so izstrel, let in pristanek v vodo varni. Model katapulta dimenzij 4000 mm x 1000 mm x 1100 mm smo zasnovali na podlagi analitičnih izračunov. Analitično smo izračunali najvišjo višino leta, hitrost pri pristanku, razdaljo od vrtišča do izstrela in dolžino leta. 3-D model katapulta smo izrisali s programsko opremo SolidWorks. V eksperimentalnem delu zaključne naloge smo naredili manjši prototip dimenzij 2000 mm x 300 mm x 445 mm, s katerim smo merili dolžino leta in čas izstrelitve. Vrednost najdaljšega dometa izstrelka je znašala 9,1 m. Izmerjen najkrajši čas izstrelitve bremena s testnega katapulta je bil 0,292 s. Rezultate prototipa smo nato primerjali z analitičnimi izračuni. Hydraulic catapult represents an innovation in the world of adrenaline adventures which is becoming increasingly popular. Catapult works by accelerating the circle with a construction arm and shoots a person into the water in the highest position. In doing so, we must be careful that the launch, flight and landing in the water are safe. The catapult model of dimensions 4000 mm x 1000 mm x 1100 mm was designed based on analytical calculations. We have calculated the highest flight height, the speed at landing, the distance from the pivot to the launch and the flight length. The 3-D model of the catapult was drawn with the SolidWorks software. In the experimental part of the final project we made a smaller prototype dimension of 2000 mm x 300 mm x 445 mm with which we measured the length of the flight and the time of the launch. The value of the longest range of missile was 9,1 m. The minimum time taken to launch the load from the test catapult was 0,292 s. The prototype results were then compared with analytical calculations. katapulti hidravlični valji potni ventili prototip katapulta poševni met adrenalinsko doživetje catapults hydraulic cylinders control valves catapult prototype projectile motion adrenaline experience true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-20 14:55:06 2017-09-20 14:55:06 2022-08-10 06:28:18 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 201335 1211.pdf 1211.pdf 1 E5DA7B96791FE456F677F76DA12723D0 a8e655080b35762cca18444910df07a23e55d422a4845ad20b2842cf0504594b c6a64e78-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/d91fab57-58d7-4a6b-bac1-a500f25ac014 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104124 Fakulteta za strojništvo 0 0 0
