A Dynamic Analysis of a Poly-Articulated Robot

Autor: Sorin Dumitru, Cristian Copilusi, Nicolae Dumitru, Ionut Geonea

Publikováno v: Computation, Vol 12, Iss 8, p 156 (2024)

This paper studies the kinematics and dynamics of a poly-articulated robot. The robot can be used in hardly accessible places and special environments. The poly-articulated robot includes two main parts: a flexible unit and an actuation unit. The fle

A Novel Exoskeleton Design and Numerical Characterization for Human Gait Assistance

Autor: Cristian Copilusi, Marco Ceccarelli, Sorin Dumitru, Ionut Geonea, Alexandru Margine, Dorin Popescu

Publikováno v: Machines, Vol 11, Iss 10, p 925 (2023)

This paper addressed attention to the design of a new lower limb exoskeleton that can be used for human gait assistance as based on kinematic considerations. The designed leg exoskeleton had on its own structure a combination of three mechanism types

Impact Dynamics Analysis of Mobile Mechanical Systems

Autor: Sorin Dumitru, Andra Constantin, Cristian Copilusi, Nicolae Dumitru

Publikováno v: Mathematics, Vol 9, Iss 15, p 1776 (2021)

The current paper focuses on the impact phenomenon analysis, in the case of multi-body mechanical systems undergoing fast motion, due to the presence of some manufacturing and mounting errors or due to some accident during the transport mechanical sy

MODAL DYNAMIC ANALYSIS FOR THE SHAFTS OF A GEARBOX

Autor: Ionut Geonea, Alexandru Margine, Cristian Copilusi, Dragos Tutunea, Valeriu Ionica

Publikováno v: Journal of Industrial Design and Engineering Graphics, Vol 14, Iss 1 (2019)

The main goal of this paper is to determinate the deformations of the shafts of a gearbox. A CAD model of a gearbox is designed in SolidWorks. The dynamic simulation of the gearbox is performed with ADAMS multibody software. In the first step of the
