| Popis: | 96 The foot, which plays an important role while human beings interact with the ground, is not only the weight-bearing but also the shock-absorbing structure during ambulation. Recently, the foot biomechanics has made great progress in both measurement instrumentation and theoretical methodology due to the scientific advances. Finite element method (FEM) can be utilized to evaluate the stress distribution of the foot beforehand, and probe into the biomechanics of the foot. So as to obtain reliable and precise analytic results, it is imperative to establish one intact and rational foot finite element model. While we establish such a complicated model, the geometry and establishing procedures are considerably significant. Based on the experience of using FEM to do biomechanical researches in the lab, this research used computer-aided programs to build a 3-D normal foot finite element model. Furthermore, we investigated the influence of different procedures and methods. In this research, we used two programs - ANSYS and SolidWorks for the generation of four foot models. The results in ANSYS Workbench showed that the model 4 is better than the others, no matter in geometry or mesh. Thus it can be seen that the model 4 is more rational and acceptable than the other three models, and it is relatively the appropriate way to establish such a complicated and irregular model. |
