Paper Abstract

This paper mainly focuses on the impact of clearance joints on morphing wing mechanism and the way to alleviate such influences. Firstly, a new kind of multiple-closed-loop mechanism for morphing wing is proposed. The dynamic modeling approach is introduced with clearance joints in mechanism. Several analyses are conducted for the impacts of clearance joints and significant conclusions are obtained for the tolerance allocation. The improved artificial fish-swarm optimization algorithm is proposed for the optimization of alleviating the effects of clearance on morphing wing mechanism. Finally, a prototype is produced and experiment is conducted to verify the efficacy of optimization.
