Research ArticleOpen accessPhrase in the titleDynamic Synthesis of a Dual-Clutch Automatic GearboxesRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuRelatively recent have occurred dual-clutch automated boxes, which promise a lot in the field and can be used successfully in cars and trains as well as in the aerospace industry. This paper wants not only to present such a gearbox but also to realize its dynamic synthesis, based on the engineering optimization of the mechanical efficiency achieved in each used … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 8 May 2018 · 7,947 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDynamic Synthesis of a Classic, Manual GearboxRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuToday, various types of gearboxes have been introduced into the vehicles to change the way the classic manual gearboxes work, such as automatic gearboxes, semi-automatic, continuous variable, dual-clutch automatic gearboxes etc. However, most gear shifters for in-service vehicles are still classical manuals, which is why their optimal synthesis based on their dynamics and especially on optimal performance is now more … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 30 Apr 2018 · 8,634 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsGeometric-Cinematic Synthesis of Planetary MechanismsNicolae Petrescu, Florian Ion Tiberiu PetrescuThe simple planetary mechanism is geometrically synthesized by determining the four tooth numbers of the component wheels. There are four main conditions that if not obeyed the mechanism will be blocked, will work with interruptions, or will not work at all. (a) The first condition in the geometric-kinematic synthesis of a simple planetary is the uniform loading of satellites (satellite … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 28 Aug 2018 · 7,458 accessesView PDF Cite
