| Summary: | 碩士 === 正修科技大學 === 機電工程研究所 === 102 === The knee joint is a very Important organ of human beings is responsible for load transmission and movement.
When the basic knee movements are seriously affected by obtain Rheumatoid Arthritis, Degenerative Joint Disease , tissue degradation due to aging or by sports injuries, and influence the quality of life dramatically, caused walking and bending the knee difficulty ,then knee surgery is needed to be performed.
This research plans after the lower limb surgery the leg walk auxiliary tool that uses carries on the discussion and improvement, and designs a walk auxiliary tool to improve its gait of walk. Using the synthesis and analysis principle, designs to be similar to the recovery auxiliary tool of lower limb of person activities .After integrating all the collected information as the design input, theories of mechanism structure synthesis, dimension synthesis, mechanism analysis are utilized to develop a mechanism design of auxiliary for lower limb disabled people to walk. The Solidwork, a CAD software, is used for solid modeling and the Visual Nastran, a CAE software, is applied for motion simulation. The results of computer simulations of walking .
The complete finite element model to perform impact force analysis, including modal analysis, dynamic response of single and continuous impact, stress and strain analysis, etcis required.
Key word :Human knee, Dynamic characteristic, Exoskeleton, Finite Element Analsys
