Abstract:  An upper limb wearable industrial assembly anti-vibration exoskeleton was proposed as an intervention measure for hand-arm vibrations. A parametric human-machine coupling simulation model was established by ADAMS. To optimize the structural parameters of the exoskeleton damping units， a single-factor vibration response analysis was conducted on the exoskeleton damping unit structures. It is found that the damper damping coefficient and installation positions were the key factors affecting the damping performance of the exoskeletons， and the front and rear spring stiffnesses of the shear damping structure were better when taken differently. The best combination of the modified factor levels was obtained through cross-orthogonal tests. The vibration reduction performance of the exoskeleton prototype was evaluated by vibration resistance tests using contact pressure and weighted vibration values as indicators. The exoskeletons reduce contact pressure by approximately 39.9% in riveting period and 49.4% in intermittent period. Wearing the exoskeletons reduce the daily contact vibration values by 15.1% and increase the riveting efficiency by up to 18% in a single day. The changes in contact pressure and vibration values demonstrate that the exoskeletons provide vibration reduction and tool support.
