Description
  • The paper deals with modelling and dynamical analysis of mechanical systems composed of rotors and a stator mutually coupled by gear and bearing discrete coupling. Rotors - shafts with fixed rigid gears - and a stator are considered as flexible bodies. Complex gear couplings between shafts with gears are presented. Model of rolling-element bearings representing couplings between rotors and a stator respects real number of rolling bodies and roller contact forces acting between journals and outer housing. This new approach allows to model and analyse the flexible stator dynamic response within the framework of a whole complex rotor-stator system. Influences of rotors unbalance and gears eccentricity on stator vibration and noise are investigated. Numerical experiments by means of simple test-gearbox are presented.

  • Článek se zabývá modelováním a dynamickou analýzou mechanických systémů složených z rotorů a statoru vzájemně spojených zubovými a ložiskovými vazbami. Rotory a stator jsou uvažovány jako poddajná tělesa. Je využit komplexní model zubové vazby mezi jednotlivými rotory. Model valivé ložiskové vazby respektuje skutečný počet valivých elementů a kontaktních sil mezi čepem a vnějším kroužkem ložiska. Tento nový přístup umožňuje analyzovat dynamickou odezvu poddajného statoru v rámci celého systému. Dále jsou studovány vlivy nevyváženosti rotoru a excentricity ozubených kol na kmitání a hluk statoru. Jsou prezentovány výsledky numerických experimentů. (cs)
