Distributed Shape Optimization of Compliant Mechanisms Using Intrinsic Functions

Abstract

Mots-clé: Stabilité transitoire, Flexible alternating current transmission system (FACTS), Advanced static var compensator (ASVC), Commande floue, Commande neuro-floue.Cet article présente une étude sur l'influence d'un dispositif FACTS sur l'amélioration de la stabilité transitoire d'un système de puissance électrique. On se propose d'étudier dans ce travail deux méthodes de commande non linéaires. En premier lieu on va introduire, dans le système de commande, un régulateur flou de type PD. Par la suite, et pour une grande performance de réglage, le contrôleur flou sera remplacé par un régulateur neuro-flou. À la fin de cet article, une simulation numérique par ordinateur illustre les résultats obtenus en utilisant les deux types de réglage.

Inverse finite element method for large‐displacement beams

“…A simple compliant gripper was proposed by Lan and Cheng [16], which allows to grab an object of a certain size and shape when acted upon. They carried out a direct analysis using intrinsic functions to parameterize the topology and the generalized multiple shooting method (GMSM) to analyze the deflection of the mechanisms.…”

“…Finally, two examples of applications in the field of compliant mechanisms analysis are shown: the design of a flexible gripper previously studied by Lan and Cheng [16], and the design of an S-type flexible clutch.…”

Novel Quasi-Passive Knee Orthosis with Hybrid Joint Mechanism

“…Its cross sectional geometry is rectangular. The force vs. displacement curve of the spring is approximated by a general shooting method, as described by Lan and Cheng (2008). Implementing a more accurate finite element analysis was not computationally efficient for the synthesis, due to large displacements and nonlinear geometries.…”

Wave mixing in coupled phononic crystals via a variable stiffness mechanism

“…Traditionally, variable stiffness mechanisms have been widely used for engineering applications, such as vibration isolation systems (VIS) [29,30], robotics [31,32], and rehabilitation devices [33]. Only recently have researchers adopted variable stiffness mechanisms for the manipulations of mechanical waves in PCs.…”
