Abstract:
BACKGROUND:Pelvis is the most complicated structure of human body, and many scholars have devoted themselves to its biomechanical study. However, it is difficult to construct the pelvic finite element model containing main muscles and ligaments, as a result of its irregular shape and complicated structure.
OBJECTIVE:To establish a normal human pelvis three-dimensional finite element model and provide digital model for the subsequent biomechanics analysis of pelvis.
METHODPelvic CT images of healthy male volunteers were stored in DICOM format and then put into Mimics 10.01 software for three-dimensional medical image reconstruction. The files were imported into reverse engineering software Geomagic studio 11 for surface processing and establishing surface model;then the surface model was introduced into finite element analysis software Ansys 14.0 for finite element meshing.
RESULTS AND CONCLUSION:A normal adult pelvis three-dimensional finite element model was developed, including 818 294 units and 149 290 nodes. Based on the CT images, we established pelvic finite element model, which have good accuracy, anatomical and geometric similarity, and could provide the basis for subsequent biomechanics analysis of pelvis.
