Abstract

The A detailed 3D finite-element analysis model of a human foot has been developed by converting CT scan images to 3D CAD models in order to analyze the distribution of plantar pressure. The 3D foot model includes all muscles, bones, and skin. On the basis of this model and the pressure distribution results, shoes for diabetes patients, which can make the plantar pressure distribution uniform, may be designed through finite-element contact analysis.

족저부의 압력 분포를 해석하기 위하여 인체에 근접한 족부 상세 해석용 모델을 개발하였다. 이 상세 해석용 모델은 족부의 단층촬영 영상(CT scan image)으로부터 밀도 차이에 따라서 골격부와 피부 및 피하조직을 각각 3D CAD 모델로 변환한 후에 결합하여 구성하였며, 근육과 뼈, 피부 모두를 반영한 3D 족부 유한요소해석 모델로 개발하였다. 개발된 3D 족부 유한요소모델에 대하여 NASTRAN의 접촉해석을 수행하여 족저압의 분포를 계산하였으며, 이러한 결과는 균일분포압력을 작용시키는 당뇨병 환자용 신발 설계의 기초 자료로 활용될 수 있다.
