DYNAMICS MODELLING OF A PARALLEL FLIGHT SIMULATOR
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2013, Vol 58, Issue 3
Abstract
Recursive matrix relations for dynamics analysis of a parallel manipulator, namely the spatial flight simulator, is established in this paper. Knowing the general motion of the platform, the inverse dynamics problem is solved using an approach based on explicit equations of parallel robots dynamics. Finally, some simulation graphs for the input forces and powers are obtained.

AN APPLICATION OF THE OPTIMAL AUXILIARY FUNCTIONS TO BLASIUS PROBLEM
In this work, a new procedure namely the Optimal Auxiliary Functions Method (OAFM) is proposed to obtain an explicit analytical solution of the Blasius problem. Our solutions are compared with those obtained by numerical...
CHECKING ROBUSTNESS FOR A CONCRETE ROADWAY VIADUCT
Experts’ pursuits in constructions are connected now with the structural robustness’ notions and how to prevent the partial, full or disproportioned collapse. The question: “What is robustness?” has by far no unitary and...
BRANCHED SYSTEMS WITH NONLINEAR KINEMATICS – COMPUTER-AIDED ANALYSIS & DESIGN
This paper presents a computer-aided modeling way of the branched systems with nonlinear kinematics that make possible the design and the analysis, as well. Being very complex systems, the elasto-dynamic study of the rea...
USE OF GENETIC ALGORITHMS FOR FITTING THE BOUC-WEN MODEL TO EXPERIMENTAL HYSTERETIC CURVES
In this paper a Genetic Algorithms (GA) method is developed to identify the Bouc-Wen model parameters from the experimental data of periodic loading tests. It is considered an extension of classical model in order to inc...
INTERNAL FORCES IN DYNAMICS OF A TRANSLATIONAL 3-PUU PARALLEL ROBOT
Matrix relations in dynamics analysis of a spatial 3-PUU translational parallel manipulator are established in this paper. Giving the evolution of the platform, an inverse dynamic problem is solved based on a set of recu...
