STABILITY OF NONLINEAR DYNAMICAL SYSTEM MOTION UNDER CONSTANTLY ACTING PERTURBATIONS [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2019
We consider the motion of a mechanical system with several degrees of freedom near zero of the phase space of states under conditions of constantly acting small perturbations. The generalized forces are represented in the dynamic equations by homogeneous

Reliability of Mechanical System of Systems

open access: yesComputer Science & Information Technology, 2018
In this paper, we present a new methodology about reliability of systems of systems. We present also an example which combines the information transformation in complex systems and virtual design of this system based on finite element analysis. This example is help to balance the performances and the costs in complex system, or provide the optimal ...

A power-based perspective of mechanical systems [PDF]

open access: yes, 2005
This paper is concerned with the construction of a power-based modeling framework for a large class of mechanical systems. Mathematically this is formalized by proving that every standard mechanical system (with or without dissipation) can be written as ...

The modal analysis of a two-link mechanical system of a robot manipulator [PDF]

open access: yes, 2022
The method of calculation of natural frequencies and forms of oscillations of a two-link mechanical system of a robot manipulator is proposed. Links of the system are considered as straight rods with a step change of cross-sectional parameters.
