题目：Reconfigurable Aerospace Systems
Fengfeng(Jeff) Xi obtained his Ph.D. degree from the University of Toronto andconducted his NSERC Post-Doctoral research at McGill University. He gainedextensive industrial experience through seven years of work as project leaderat the National Research Council of Canada (NRC). Currently, he is a Professorwith the Department of Aerospace Engineering of Ryerson University, in Toronto,Canada, NSERC Senior Industrial Research Chair,Director of Ryerson Institute for Aerospace Design and Innovation(RIADI). Over the last two decades, he has been working extensively in the areaof reconfigurable systems, and founded the Reconfigurable Systems Laboratory(RSL) at Ryerson. His initial work included discrete reconfigurable systemssuch as reconfigurable serial and parallel robots, with applications toabrasive machining and riveting. His current work focuses on continuous (shapeadaptive) reconfigurable systems such as morphing wings and cabins. He willserve as the Conference Chair for the 2021 IEEE/IFToMM International Conferenceon Reconfigurable Mechanisms & Robots (ReMar2021).
In this talk areconfigurable system design methodology will be presented based on modulesthat are fundamental to realize system reconfiguration. The presented methodconsists of three pillars: module determination, module design and modulesynthesis. Module determination is to identify basic elements from a given setof functions for reconfiguration using axiomatic theory. Module design is togenerate basic adaptive elements for reconfiguration using metamorphic theory.Module synthesis is to combine these elements to form a reconfigurable systemagainst a set of criteria using multi-disciplinary design optimization (MDO)theory. The developed method has been applied to design a number ofreconfigurable aerospace systems. Examples of continuous (shape adaptive) reconfigurablesystems comprise morphing wings and morphing cabin. Examples of discretereconfigurable systems contain reconfigurable aerospace manufacturing systemsfor riveting and polishing. Real-case designs will be presented to demonstratethe effectiveness of this science-based design methodology for reconfigurablesystems.
