Research ArticleOpen accessIn the abstractCase Study on the Effects of Plan Irregularities on Seismic Performance of StructuresEduardo Flores, Tadeh ZirakianGeometric configurations, such as large openings, re-entrant corners, and discontinuity in diaphragms, are very common in architectural design but are seen as undesirable for structural performance during earthquakes. The lateral systems in a structure resist the strong forces induced during an earthquake, preventing damage or collapse of the structure. If these systems fail, the structural integrity of the building may … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 21 Jul 2024 · 5,723 accessesView PDFCite

Research ArticleOpen accessIn the abstractLagrange II Dynamics and that of Forces Exemplified on a Basic Robot, 2 DoFRelly Victoria Virgil PetrescuThe paper presents two dynamic methods applied to a basic articulated robot, 2 DoF, the first being an original adaptation of the type II Lagrange equations and the second being a dynamic method based on the influence of the forces in the robot mechanism. Both methods are original, as they were designed and applied by the author to a 2 … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 2 · 26 Jul 2023 · 5,752 accessesView PDFCite
Research ArticleOpen accessIn the abstract4D Printing: Technology Overview and Smart Materials UtilizedAntreas Kantaros, Theodore Ganetsos, Dimitrios Piromalis4D printing is a cutting-edge technology that allows for the creation of dynamic, self-assembling structures by utilizing cutting edge, newly introduced smart materials. It builds upon traditional 3D printing by adding the dimension of time, allowing printed objects to change shape or behavior over time. This is achieved through the use of smart materials, such as shape memory alloys or … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 13 Mar 2023 · 14,196 accessesView PDFCite

Review ArticleOpen accessIn the abstractInternal Combustion Engines ForcesRelly Victoria Virgil PetrescuThe paper presents an algorithm for determining the dynamic parameters of the internal combustion mechanism. Shows the force distribution (on the main engine mechanism) on internal combustion engines. Dynamically, tools can be distributed in the same way as forces. Practically, in dynamic regimes, speeds have the same synchronization with forces. The method applies separately for two distinct situations: When the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 23 Jul 2019 · 6,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractMachine Motion Equations Presented in a New General FormatNicolae Petrescu, Florian Ion Tiberiu PetrescuConsidering the increased importance of robots nowadays, when no large factory or factory can work without robots, we want to present in the work the motion equations of the machine in an original form, both in terms of aspect and their deduction. The machine's motion equations can be used in dynamic calculations at any type of machine, whether it be … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 22 May 2019 · 6,131 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Yield of the Thermal EnginesNicolae Petrescu, Florian Ion Tiberiu PetrescuThis paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined. The method applies separately for two distinct situations: … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 6,191 accessesView PDFCite
Review ArticleOpen accessIn the abstractSomething about a Railbound Forging ManipulatorRelly Victoria Virgil PetrescuHeavy payload forging manipulators are mainly characterized by large load output and large capacitive load input. The relationships between outputs and inputs have greatly influenced the control and reliability. Forging manipulators have become more prevalent in the industry today. They are used to manipulate objects to be forged. The most common forging manipulators are moving on a railway to have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 8 May 2019 · 7,086 accessesView PDFCite
