Applying Monte-Carlo Methods to Geometric Deviations Simulation within Product Life Cycle
Résumé
Today, product designers work on the nominal model of the product within a CAD system. Most of the behavioral simulations and thus performances prediction are carried out using this model. For real products, geometric deviations are generated and accumulated at every stage of its life cycle, especially the manufacturing and assembly stages. These deviations can make the designed product not to meet fully and systematically the requirements of the customers and the users. Thus, it is necessary to take the geometric deviations of a product generated during its life cycle into account the real performance prediction. In this paper, Monte-Carlo methods will be applied to simulate the geometric deviations of a product during its life cycle. As a result, the product designers not only make the performance simulations on the nominal product model but also take into account the geometric deviations of products. They can thus ensure that the product they are designing would have "real" performances satisfying customers and users.
