Simulation en ergonomie : facteur d'innovation dans la conception de produits : application à la conception de systèmes de travail

Abstract : This research is positioned in the Industrial Engineering field and it is dealing with the human factor integration in the design process of products and associated work systems. Using the knowledge, methods and specific tools of two disciplines (Engineering Science and Social and Human Science), the research proposes a human-centered design methodology that is allowing a better Ergonomics Analyse Products Design articulation, from the very beginning to last stage of process. At the heart of this methodology there is a numerical simulation method of Gestural and Posturales Activities of Human that is possible with the support of the numerical mannequins which are the 3D human models. So, this method and the MANERCOS associated tool permit us to propose a new way to design and re-design the products/work systems which allows the innovation by a better consideration of the human characteristics: anthropometrical, biomechanical etc By the application to the work systems design, we show particularly how the proposed methodology allows to detect and to estimate some of the risk factors of Work Related Musculoskeletal Disorders (WRMD) resulting from the working conditions, the tools and workplaces design etc., and how to contribute in this case to the prevention of the professional diseases in constant increase for several years. More specific, the proposed methodology bring together all the actors of design process to define, to test, to estimate and to validate the numerical mock-ups of future work systems, adapted to the future operators, in terms of health, safety, comfort and efficiency at work. So we reveal capacities and the effectiveness of the MANERCOS tool, but we also show the way to evolve it in order to make better the "ergonomist - designer" cooperation within the design process. Particularly, the new features brought to this numerical mannequin, coupled at a measure tool of movements and efforts (CAPTIV tool) and associated in prospect at a virtual reality platform, will permit a better evaluation and prediction of the risks of Work Related Musculoskeletal Disorders (WRMD), by taking into account the Gestural and Posturales Activities
