Sequencing for Process Planning by Genetic Algorithm important function in process planning elaboration. It conditions the choice of machines, the feasibility and the cost of the process plan. We suggest a GA that allows the handling of conditional precedence constraints, the representation of different process planning solutions and the discovery of

A Tool for Verifying the Local Quality of a 3D F.E. Analysis in Designning criteria nearly always involve local quantities (stresses in specified zones, Von Mises’ stresses, displacements, stress intensity factors, ...). In current industrial practice, these quantities are evaluated using F.E. analysis. Even if the mechanical model chosen is adequate (good description

A Unified Jacobian-Torsor Model for Analysis in Computer Aided Tolerancingdel. The former is based on small displacements modeling of points using 6x6 transformation matrices of open kinematic chains in robotics. The latter models the boundaries of 3-D tolerance zones resulting from a feature’s small displacements using a torsor representation with constraints. The propos

Inertial Tolerancing in the Case of Assembled Products USL]. Several approaches have been proposed to determine this tolerance, the main results of which be referred. Inertial Tolerancing consists in tolerancing the mean square deviation from the target rather than the distance. This alternative has numerous advantages over the traditional approach, pa

An Interactive Decision Support System for Unidirectional TolerancingThe foundation of our work is an efficient representation of a mechanical assembly based on graph theory. From this model, we can determine all the configurations of an assembly. An extended syntax for the functional constraints permits then to generate automatically all the tolerance chains. The fi

Improvement of the Simulation Tools Dedicated to Composite Structures Subjected to Crash Loadsimposed on industrialists particularly in terms of active safety. Moreover, among of all the materials used for design, some such as composite materials require special attention. It is consequently within this framework that we propose to describe in this paper the contributions which were made to

On the Kinematic Calibration of a Stewart Platform parallel robots is proposed by the authors and applied in the case of the Stewart platform. Thus, an accuracy model of the Stewart platform is established, taking into account the errors of the geometrical parameters. Next, on the basis of the precision model and the experimental data for the accur
