Establishment of Three-Dimensional Finite Element Model and Biomechanical Analysis of Index Finger by Polyetheretherketone
摘要
Abstract
The three-dimensional finite element model of index finger was established,and the attributes of polyetheretherketone material were assigned to analyze the stress distribution of each phalanx of index fin-ger under different loads.A healthy male volunteer was selected to perform CT scanning on his left hand.The scan data was imported into Mimics 21.0 software to obtain the point cloud data of index finger,and then imported into UG 12.0 software for reversed processing to establish index finger model.Finally,the data were put into the Workbench 2020R1 software.Ten,twenty,thirty,forty and fifty Newton loads were applied along the longitudinal direction of phalanges to analyze the stress distribution of index finger bones.The results show that a high-precision three-dimensional finite element model of index finger has been established,with a total of 551 410 nodes and 392 047 tetrahedral elements.With the increase of load,the peak is stress of index finger bones ranges from 0.37 to 5.96 MPa,and the overall stress of the distal phalanx was significantly higher than that of other bones,of which the proximal phalanx suffers the smallest amount of stress.It can be concluded that Mimics and Workbench software can be used to estab-lish the index finger finite element model with high accuracy so as to conduct qualitative and quantitative analysis of index finger biomechanics,providing a theoretical basis for polyether ether ketone material as index finger replacement material.关键词
