摘　　要：有限元作为重要的生物力学研究手段,已经被广泛用于足部生物力学的研究。本研究旨在通过对一名成年男子右足进行有限元模型的建立,并用Footscan 1m板足底压力测试系统采集的数据对其可靠性进行验证,从而完善足部有限元模型的构建方法,为今后足部生物力学的研究提供更为有效的数据支撑。研究表明,以此方法建立的足踝部位的有限元模型分析结果与Footscan足底压力数据相比,尽管二者在足底压力分布上存在差异,但足底压力集中部位基本一致。试验结果证明了采用此方法建立有限元模型的可靠性和后期应用的可行性。The method of finite element model is widely used in foot biomechanics as an important method in biomechanics study. The 3D reconstruction of CT images from the right foot-ankle was built by Patran software, meanwhile the Footscan plantar pressure system was also used to verify the FE model. The results show that due to the relative bone FE model without ligament and fat pad, there were differences between the FE model and the foot plantar pressure distribution, however the region of pressure concentration was similar. Moreover, the construction and analysis method of the FE model in our study can be used in the further experiments.
