Abstract

In order to evaluate anti-vibration exoskeleton's ability to reduce vibration of aerial assembly power tools, aviation assembly riveting process was simulated and riveting test of its vibration reduction performance was designed. Then a weighted average method was proposed to comprehensively evaluate its performance with mean value of pressure signals and weight coefficient of different postures during riveting period and riveting interval under conditions of wearing or not wearing exoskeleton. The results show that anti-vibration exoskeleton reduces 59. 9% of riveting vibration and 50. 4% of palm pressure when impacted by riveter for tester 1, and 49. 5% and 36. 9% respectively for tester 2. Its reduction performance is negatively related with pressure of riveting interval while wearing exoskeleton at 0. 01, and it has no correlation with that in case of not wearing exoskeleton and riveting operating posture. It is also found that exoskeleton can reduce vibration of riveter by more than 50% and has an important protective effect on arms of assembly workers. © 2019 China Safety Science Journal.
