ABSTRACT
Military exoskeleton system (EXO) is a kind of accompanying intelligent equipment system which is worn on individual soldier's body. Through synchronous following human movement, assisting individual soldier's load-bearing assistance and load-bearing mobility, it can effectively enhance individual soldier's carrying capacity and rapid mobility. EXO has a wide range of military needs in the fields of backloading and moving support, material accompanying, border patrols support and so on.
The development of EXO in China is still in the stage of research and experiment. The technical difficulty lies in the flexibility of exoskeleton to human motion, that is, the flexibility of exoskeleton robot. Therefore, the thesis has completed structure design and optimization of EXO. The main work is summarized as follows:
Firstly, the analysis of Human Kinematics. In order to optimize the coordination between the EXO and the soldier, the design size of the EXO should be as close as possible to the human body size, and its trajectory should be as close as possible to the normal human motion.
Secondly, structural design of External Skeleton Joints of Military Flexible Lower Limb exoskeleton robot (FLLX). The design of FLLX includes hip joint, knee joint, ankle joint, joint connection and driving part.
Thirdly, the statics analysis of the key components of FLLX. ANSYS Workbench statics analysis module is used to analyze the static deformation and stress of key parts of External Skeleton ankle joint. So, stress distributions were obtained and analyzed. The static strength and stiffness of mechanical structure are verified.
