Abstract

International audience; Rework tasks in collaborative development projects dealing with immature design concepts are very frequent and are responsible of cost overruns and schedule delays. Taking into account uncertainty and accuracy of models (and data) improves decision making according to strategic orientation for product development. Based on a real design of light, slender but rigid collectors’ supports, multiple tools have been developed and tested to support decision making at different stages of development process. The objective of this paper is to investigate the integration of these accuracy evaluations into the design process. This proposal is validated by the industrial development and validation.

Abstract

International audience; Hydrogen stock vessels add new product specifications because of higher pressure use. Today static application leads up to 700 bars. But pressure devices must resist, because of certification, at 3 times pressure (2100 bars). Composite vessels give material-structure potential solutions. But designers face limits of knowledge due to actual good practices of thick composite structures use. This paper presents levels of knowledge enrichment for designers (multi-scale experiments and models), analysis of process influence on models improvement, and a discussion for an efficient testing strategy (meaning virtual testing in order to reduce the number of tests and their costs).
