摘要

This paper presents a method for designing heat-reversible snap joints, locator-snap systems that detach non-destructively by heating a certain location of parts. It is expected to dramatically improve the recyclability of aluminium space frame (ASF) bodies by enabling clean separation of frames and body panels. Extending our previous work on the sequential design of the locators and heating area (Shalaby and Saitou, 2005), the method simultaneously optimises locators, heating area and snaps for ensuring joint detachment with minimum heat and avoiding resonance due to vehicle vibration. A multi-objective genetic algorithm is utilised to search for Pareto optimal design alternatives.
