چکیده

In the context of structural optimization, we propose two natural extensions of the level set method for the design of compliant mechanisms. Two new objective functions are introduced, well suited to the automatic design of compliant mechanisms, and a strategy for the design of mechanisms adapted to multiple loads is proposed. This work is illustrated with several numericals examples. RÉSUMÉ. Dans le cadre de l’optimisation de structures élastiques, nous proposons deux extensions naturelles de la méthode des lignes de niveaux qui peuvent s’avérer utiles aux concepteurs de micro-mécanismes. Nous introduisons une nouvelle fonction-coût, inspirée d’un critère d’optimisation largement utilisé dans le domaine de la conception de mécanismes, ainsi qu’une stratégie pour traiter le cas de mécanismes adaptés à plusieurs chargements (multichargement). Ce travail est illustré de quelques exemples numériques.

Large Deflection Analysis of Compliant Beams of Variable Thickness and Non-Homogenous Material under Combined Load and Multiple Boundary Conditions

This paper studies a new approach to analyze the large deflection behavior of prismatic and non-prismatic beams of non-homogenous material under combined load and multiple boundary conditions. The mathematical formulation has been derived which led to a set of six first-order ordinary differential equations. The geometric nonlinearity was solved numerically using the multiple shooting method co...
