20.500.12556/RUL-149793 Analiza pasivnega umirjanja torzijskovpetega nosilca z dvema mirilnima masama Analysis of passive damping of a torsionally mounted beam with two damping masses Mehanska nihanja so v različnih mehanskih sistemih, kot so stroji, konstrukcije in vozila, pogosto neželeni. Ta nihanja lahko privedejo do zmanjšane učinkovitosti sistema, večje obrabe komponent in celo do okvare ali zloma struktur. Zato je pomembno umirjanje teh nihanj za boljše delovanje in zanesljivost mehanskih sistemov. V zadnjem času se intenzivno raziskujejo in uporabljajo tehnologije za zmanjšanje vibracij, vključno z aktivnimi in pasivnimi dušilci nihanj. Diplomska naloga se osredotoča na uporabo modela z eno ali dvema masama na vzmeti za pasivno umirjanje nosilca, ki je obremenjen s harmonsko motnjo. Cilj te naloge je raziskati vpliv dodatnih mas na vzmeti v sistemu za pasivno umirjanje nihanj. Raziskava si prizadeva razumeti, kako ti dodatni elementi vplivajo na odziv v primerjavi s sistemom brez teh elementov. Prav tako želimo primerjati sistema z eno ali dvema dušilnima masama in ugotoviti v kakšnih pogojih delujeta ter prepoznati prednosti in slabosti uporabe teh sistemov za umirjanje nihanj. Mechanical vibrations in various mechanical systems, such as machinery, structures, and vehicles, are often undesirable. These vibrations can lead to reduced system efficiency, increased wear of components, and even failure or breakage of structures. Therefore, damping these oscillations is crucial for better performance and reliability of mechanical systems. In recent times, technologies to reduce vibrations, including active and passive vibration dampers, are being intensively researched and applied. This thesis focuses on using a model with one or two masses on a spring for passive damping of a beam subjected to harmonic disturbance. The aim of this work is to investigate the impact of additional masses on springs in the system for passive vibration damping. The study strives to understand how these additional elements affect the response compared to a system without these elements. We also aim to compare systems with one or two damping masses and determine under what conditions they operate, as well as identify the advantages and disadvantages of using these systems for vibration damping. torzijsko vpet nosilec harmonično vzbujanje pasivno umirjanje drugi Newtnov zakon numerična analiza Python torsionally mounted beam harmonic excitation passive damping second Newton's law numerical analysis Python true false false [O.
