Abstract

Abstract:

BACKGROUND: To overcome the disadvantages of traditional mechanical analysis of specimens, and establish the finite element model of realistic foot, are the important basements for the finite element mechanical analysis on foot.
OBJECTIVE: To establish three-dimensional finite element model of foot and lay the foundation for the finite element analysis of normal foot and foot injury.
METHODS: A healthy female volunteer was involved in this study and was detected with spiral CT scanning on the feet. The resulting image was used to reconstruct the three-dimensional model by using Mimics software. Then entity model was generated in Geomagic software. Finally three-dimensional finite element model was established based on the digital main structure in Ansys.
RESULTS AND CONCLUSION: The established finite element digital model of human foot included all bone, cartilage and ligament, skin and soft tissue. The three-dimensional finite element model of human foot was established based on CT data and using Mimics, Geomagic, Ansys softwares. The established model had similar size and shape with skeletal mode, and can rotate freely in any angle for a variety of measurement, the foot bones can be arbitrarily split or merge, which is suitable for biomechanical analysis.
