Compactness is becoming a driving force in today's mechatronic systems. However geometrical integration usually happens too late in the design cycle of these systems, to be optimum. In this paper, we proposed to integrate geometrical specifications in the early design during the emergence of physical architecture in SysML, through a geometrical profile. This adding information could be used to compare...
This paper presents an original friction measurement setup. It is designed to uncouple normal and tangential loads. Friction measures acquired with this setup present a high signal to noise ratio. This friction experimental device allows characterizing various types of surfaces and several levels of excitation from static strain to dynamical motion including micro-sliding and macro-sliding. A measurement...
Industrial constraints to make design choices for new performing products increase, especially when design integrated mechatronic system. It also emphasizes the need of a mean to measure the integration level of a mechatronic system to help designers to make their architecture choice. We focus our study about the use of metrics, as decision aide-making support for preliminary design of mechatronic...
Optimizing a multidisciplinary integrated system design, taking into account multi-criteria interacting requirements, is a real challenge in mechatronic design. A new multi-criteria indicator for mechatronic system performance evaluation is formulated and described in this paper. An example of mechatronic system design is considered to validate the presented approach. It will be shown that the new...
In this study, we propose to integrate the entire downward side of the design V-cycle in order to achieve to a modelling continuity through the different levels of design approach (requirements, functional, components and structural). For this, we propose a hybrid methodology based on several tools, languages and methodologies such as SADT, SysML, Modelica, in a single environment: Dymola.
The slip casting and subsequent pressureless sintering route has been revealed as a powerful method to obtain a high-density silicon nitride. The optimisation of the slip casting preparation and of the sintering conditions has been investigated. The relation between microstructure, mechanical properties and thermal shock behaviour of Si 3 N 4 is also outlined. Finally, this process...
