acestuia. De asemenea cresterea vitezei de circulatie influenteaza cu o pondere mai mare anumite aspecte ale
dinamicii vehiculului dar in principiu sunt urmarite si studiate aceleasi aspecte si fenomene ce apar in timpul
rularii.
Literatura de specialitate de actualitate este foarte bogata in studii foarte interesante, foarte multe publicatii
din tara dar in special din strainatate trateaza cu deosebit interes problemele de contact intre roata si cale care este
o problema sensibila si constituie inca un punct de atractie pentru foarte multi specialisti in domeniu:
• problemele de contact intre roata si cale in aliniament [1-4] si la trecerea peste aparatele de cale
[5], [6] sau peste lucrari de arta [7], [8].
• problema suspensiilor este studiata cu larg interes aceasta jucand un rol foarte important in
dinamica vehiculelor feroviare de mare viteza [9]
o controlul activ al vibratiilor maselor ce intra in componenta vehiculelor feroviare [10]
o studii deosebit de interesante privind problemele de amortizare in suspensii [11], [12]
o studii de disipare in amortizoare cu frictiune [13]
o studii de disipare in amortizoare vascoase [14]
• probleme de captare a curentului electric, adica studiul problemelor vibratorii ce apar la contactul
dintre pantograf si catenara [15], [16],
• studii ale sinelor de cale ferata si infuenta iregularitatilor lor asupra sistemelor componente
aferente [17]
• studii de vibratii induse de vehicule catre mediul inconjurator [18], [19]
• studii vibratorii pentru rularea pe cai ferate subterane sau tuneluri [20].
Acestea aspecte amintite mai sus reprezinta in mare o parte a problemelor deosebit de importante abordate
de catre renumiti profesori si cercetatori de renume mondial care publica articole de foarte mare interes si
actualitate in cele mai cunoscute si apreciate publicatii din domeniul mecanicii.
