ABSTRACT
In the non-obstacle construction for the handicapped life and work, benefits of the prosthesis wearers should never be neglected. Various disabled functions on the lower limb lead to a wide variety of prosthesis type and thus the prosthesis design should be a personalized design issue. A digital design and analysis platform would be very helpful to the personalized design of the prosthesis. It is the goal of this study to build up a biomechanical model of the prosthesis wearer mobility which can provide basic data model for the digital design. Based on the present on-site investigations, the research is mainly focused on modeling the climbing of the under-knee prosthesis wearers based on the experiment observation. The model would be validated by the simulation based on Poser and the results would be compared to the statistical data from the observed experiment, which validate the model itself. By transferring the model into the mathematical model combined with the finite element analysis, a digital design analysis platfonn for the limb prosthesis design suitable for more complicated motions can be established for the comfort design of prosthesis.
