Prezenta carte isi propune sa rezolve problemele principale de
dinamica, ce apar la mecanismele de distributie ale automobilelor
si autovehiculelor rutiere. Sunt modulate si luate in calcul mai
multe tipuri de mecanisme de distributie cu cama si tachet. Se
porneste cu mecanismul clasic de distributie, avand cama rotativa
si tachetul de translatie plat (cu talpa), construit clasic cu un
unghi de 90 grade sexazecimale] intre talpa si axa de translatie a
tachetului. Se continua cu mecanismul de distributie care are cama
rotativa si tachetul de translatie cu rola. Urmatorul modul
prezentat pastreaza cama rotativa si tachetul cu rola, dar acesta
din urma nu mai translateaza ci se roteste, rotatia fiind sub forma
unui balans. Ultimul modul de distributie studiat in cadrul cartii
are tot cama de rotatie si tachetul de rotatie (balansier) plat (cu
talpa). La fiecare modul se prezinta pe scurt, geometria sa,
cinematica, cinematica de precizie, cinetostatica (fortele care
actioneaza in cupla mecanismului de distributie considerat), si
dinamica mecanismului respectiv, care cuprinde doua aspecte
principale, randamentul mecanismului, si cinematica sa dinamica
(cinematica reala a mecanismului de distributie, influentata de
toti parametrii functionali, inclusiv de fortele de inertie). The
first chapter presents a brief history of the emergence and
development of the internal combustion engines, because they have
developed the distribution mechanisms. The second chapter presents
some dynamic models used to study the mechanisms of distribution.
Chapter 3 presents the actual dynamics of distribution mechanisms,
exemplified by the traditional mechanism with rotary cam and
follower (flat, with translant movement). Chapter 4 makes the
dynamic analysis for traditional distribution system. Chapter 5,
dealing with dynamic study of the mechanism with rotary cam and
translant follower with roller. Chapter 6, dealing with F dynamic
module, who is still as well with a roller follower, but which has
a rotating movement. Chapter 7 (the last) presents more focused,
module H, which representing the rotary cam with flat rotating
follower. The book is written in Romanian.
