Abstract

Uspješnost izvedbe tehnoloških i konstrukcijskih rješenja primijenjenih kod razvoja
helikoptera procjenjuje se analizom spektra vibracija kojima su posada , putnici i letjelica
izloženi tijekom leta. Otklanjanje ili reduciranje dijela spektra vibracija od velike je važnosti
zbog:
− smanjenja štetnog utjecaja vibracija na posadu i putnike,
− smanjenja dinamičkih naprezanja koji uzrokuju zamor rotora i ostalih elemenata
konstrukcije
− zaštite i produženja vijeka upotrebe osjetljivih elemenata helikopterske opreme.
Tema vibracije helikoptera, te ova problematika u našoj literaturi je jako malo obrađivana.
Ovaj diplomski rad će prikazati analizu vibracija koje se pojavljuju unutar kabine helikoptera
Mil Mi-8 u određenim režimima leta na helikopteru sa ugrađenim ublaživačem vibracija na
glavnom rotoru i bez njega. Kroz analizu dobivenih podataka izvući zaključke o utjecaju
ublaživača vibracija na razinu vibracija u helikopteru Mil Mi-8.

Abstract (english)

Success of the technological and structural solutions implemented in the development
of the helicopter is estimated by analyzing the spectrum of vibrations which are the crew,
passengers and aircraft exposed during the flight. Elimination or reduction of part of the
vibration spectrum are very important because:
− reducing the harmful effects of vibration on the crew and passengers,
− reduce the dynamic stresses that cause fatigue of the rotor and other structural
elements
− preserving and extending the life of the sensitive elements of helicopter equipment .
Topic vibrations of the helicopter, and these problems in our literature is very little
elaborated.This work will show the analysis of vibrations that occur inside the cockpit of the
Mil Mi-8 in certain regimes of flight in a helicopter with built-in vibration damper on the
main rotor and without it. Through the analysis of the obtained data this work will make
conclusions about the effect of the vibration dumper on the vibrations in the helicopter Mil
Mi-8.
