Abstract
More than a multi-technology fusion, mechatronic systems are becoming more and more complex, these systems can be reconfigured with changes in the environment and states of the functional units, evaluating and improving the reliability of mechatronic system requires to take into account the reconfigurable aspect. This point has become a major challenge for reliability engineers during the design phase. Therefore their dysfunctional modeling is very difficult. This communication presents an original proposed methodology for evaluating the reliability of mechatronic system with taking account the reconfigurable aspect. This reliability model integrates the change of the configuration related to the external and internal conditions.
Highlights
Mechatronics is a concept of merger and integration in permanent evolution, Fusion means that it involves associating disciplines [1]
We focus mainly in this communication on taking account the reconfigurable aspect during evaluating the predective reliability of mechatronic systems
In order to formalize a reliability model for the concept of reconfigurable mechatronic systems, we first propose to treat the notion of reconfigurable aspect for each domain as proposed in Figure 1, and to conclude a representation for reconfiguration of mechatronics
Summary
Mechatronics is a concept of merger and integration in permanent evolution, Fusion means that it involves associating disciplines [1] (mechanical, electronic, computer, ...). According to bibloigraphy [1, 2, 3], to allow a better control of the reliability of the mechatronic systems, one must take into account its aspects: dynamic, hybrid, interactive and reconfigurable. A reconfigurable system has the ability to adapt to changes according to an internal and/or external factors, and to make changes to the configuration and fit of the structure in order to maintain its functionality with adequate quality of service, despite the presence of disturbances. In the second case, called dynamic, His goal is to dynamically adapt to specifications
