Review ArticleOpen accessEvery word in the titleMechanisms With Rigid MemoryRelly Victoria Virgil PetrescuAlong with gears, distribution mechanisms are the most widely used mechanical transmissions used over the past 300 years and will continue to be the most widespread in all industrial fields but also in other technical areas. For this reason, it was considered necessary this work, which tries to add a brick to the permanent construction of rigid memory mechanisms used … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 19 Jul 2019 · 6,162 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,981 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleDynamic Models of Rigid Memory MechanismsFlorian Ion Tiberiu PetrescuRigid memory mechanisms have played an important role in the history of mankind, contributing greatly to the industrial, economic, social changes in society, thus leading to a real evolution of mankind. Used in automated tissue wars, in cars as distribution mechanisms, automated machines, mechanical transmissions, robots and mechatronics, precision devices and medical devices, these mechanisms have been real support for … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 7,257 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStructural Analysis of Spatial MechanismsFlorian Ion Tiberiu PetrescuThe paper briefly presents how structural analysis is performed on spatial mechanisms, presenting a practical application in the mechatronics of parallel robots, especially in Steward platforms. Structural analysis always helps to better understand the phenomena and especially the way the mechanisms are made. At spatial mechanisms the problems are a little more complex than those raised by plane mechanisms. For … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 7,971 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Aspects of the Structure of Planar MechanismsRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The machine is a technical system made up of distinct kinematic component parts (called kinematic elements) which, following the imprinting of movements imposed on an element or elements (considered as leading elements), cause movements to all other kinematic elements in order to execute a useful mechanical thing, or transforming some form of energy into mechanical energy. It follows from the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Feb 2018 · 8,020 accessesView PDFCite

The modern industry, the practice of designing and building machinery is increasingly based on the results of scientific and applied … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 13 Dec 2017 · 6,846 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamics of Mechanisms with Cams Illustrated in the Classical DistributionRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,491 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeometrical Synthesis of the Distribution MechanismsFlorian Ion T. PetrescuIn this study the author presents shortly some few original trigonometric methods to make the synthesis of some main distribution mechanisms. One presents four main modules of distribution mechanisms, with rotary cam and translated or rotated tappet plane or with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. These types of distribution mechanisms … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 13 Apr 2015 · 8,858 accessesView PDFCite
