Title Programs and structural design of human upper limb exoskeleton

Abstract The human upper limb exoskeleton is an endurance mechatronic product used to enhance human upper body strength. It makes human intelligence and machine strength together organically, which can complete alone the task that cannot be completed with the person's own ability under the control of the operator, and effectively enhance the human endurance.

The exoskeleton development status at home and abroad as well as the application is introduced and the future development of this technology in prospects is analyzed in this thesis. Parameters that mechanism design of the human upper limb exoskeleton requires are determined through analysis of ergonomics, dynamics and other aspects.

Based on the analysis of working mechanism of human upper limb exoskeleton, the human upper limb exoskeleton overall program is proposed, and the structure of the mechanical part is designed and analyzed. Three-dimensional model is created using Solidworks, and then the dynamics of this system is analyzed with Adams. Shoulder, elbow of Human upper limb exoskeleton can exercise according to a predetermined trajectory under normal circumstances that is proved, and the motion law accord with human body joints, so it can help users to lift heavy objects.

Keywords：Human upper limb exoskeleton, Dynamics simulation, Mechanical structure design, Three-dimensional modeling
