Reseña del libro "Dinamica Mecanismelor de Distributie"
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.
