Research on Human-Exoskeleton Collaboration Performance Evaluation in Typical Aerospace Component Assembly Scenarios

To reduce the risk of work-related musculoskeletal disorders (WMSDs) in aerospace component assembly, this study evaluates the performance of exoskeletons in typical component assembly scenarios. Surface electromyography (sEMG) quantitatively assesses upper-limb exoskeleton assistance and hand-vibration-damping exoskeletons, while a subjective satisfaction questionnaire evaluates human-exoskeleton interaction performance. Results demonstrate that upper-limb exoskeletons reduce upper-arm fatigue by up to 45.8% in lifting tasks, and hand-vibration-damping exoskeletons decrease forearm vibration by 40% in riveting operations. Subjective feedback highlights the need to enhance exoskeleton comfort and flexibility for aerospace applications. This research provides empirical data to support the widespread implementation of industrial exoskeletons in component assembly and establishes a foundation for their further development and optimization in aerospace manufacturing.
