Brief Description :

Context:

The proposed subject is part of one of the main research themes of the DC SIREP of the G-SCOP Laboratory (http://www.g-scop.grenoble-inp.fr/), relating to modeling, simulation and optimization of disassembly operations. It follows the work already done on the identification of contacts and the generation of disassembly trajectories as well as optimization in the generation of disassembly sequences and their integration in a Virtual Reality environment.

Partners: The proposed topic is a follow-up to WP9, Task 9.1. Interaction and Manipulation within Virtual Interactive Scenes of the European Infrastructure VISIONAIR (http://www.infra-visionair.eu/) (2011-2015) and currently working with the research themes of LABEX PERSYVAL Lab, Research Actions, AAR Authoring Augmented Reality, WP2, Real-time capture and simulation of the real world. Representation and editing of virtual prototypes. Natural interaction with the augmented world, (http://www.persyval-lab.org/index.html). In addition, it is part of a joint research theme, as part of a collaboration, begun seven years ago, with Shanghai Key Laboratory of Mechanical Automation and Robotics of the University of Shanghai, China.

Description of the subject:

Literary research conducted as part of our recent work shows that existing simulation platforms are often poorly integrated into the product development process (PDP). Some approaches for the modeling of disassembly have been proposed but they do not allow to validate them because they do not take into account the effective geometry of the parts constituting the mechanical assembly. Thus, we have to define the mobility among the components by a set of intrinsic information of the contacts. We also need complete models, able to describe the allowed movements for mechanical assembly components for simulations of interactive, real-time or immersive assembly/disassembly (A / D) operations.

Objectives:

In this context, the objectives of the proposed research subject are:
- To propose a method for planning and simulating of A/D operations of the product based on LCA (Life Cycle Analysis).
- To establish a model based on the proposed method to lead to a disassembly tree based on a hierarchical analysis of the components constituting the product. The tree will generate disassembly sequences. The model will be based on the Digital MockUp (DMU) model of the mechanical assembly.
- To optimize the possible disassembly sequences according to different criteria, including the lowest cost in the current disassembly process.
- To integrate the disassembly process sequence generation method into a virtual reality (VR) system with a perception model.
- To validate the model, thanks to its integration in a restricted virtual environment allowing the simulation of A/D operations within the framework of the existing data processing environment, as its integration in the PDP for the purpose of the Lean design for disassembly.

Thus, the validation of the disassembly sequences will help the designers to estimate the level until the product can be dismantled from the initial phase of its design.
