Computer-aided Design and Finite Element Analysis of Ankle Foot Orthosis Based on 3D Printing
摘要
Abstract
Patients with ankle injuries or defects need ankle-foot orthosis-assisted rehabilitation and treatment,and it is important to design structures for fast restoration and comfortability of patients.At present,the ankle foot orthosis on the market is designed to support the back of the calf,and its structure and usage are simple.With the development of additive manufacturing technology,computer-aided design and 3D printing may assist to personalized ankle-foot orthosis processing,which not only meet the needs of different patients,but also have low costs,flexible design,ease for carry and so on.In this study,by computer-aided design and finite element analysis,two models including fixed and active structures were designed,and optimizing materials,and analyzing the deformation and stress distribution,so as to provide ideas for the optimization of 3D printed ankle-foot orthosis design and customization.The results show that the traditional ankle foot orthosis have more stable structure and durability,compared with the active ankle foot orthosis due to concentrated stress at the active site.So carbon fiber (CFRP) and polyether ether ketone (PEEK) materials are introduced to improve the structural stability and durability for the active ankle foot orthosis,meeting the needs of clinical patients.关键词
