| 目的建立成人肘关节及前臂三维有限元模型，为进一步进行生物力学研究打下基础。方法拍摄健康成人肘关节至腕关节薄层CT图像，将其导入Mimics、Hypermesh软件中建立肘关节及前臂三维有限元模型，用模型进行负荷加载实验并在LS-DYNA中运算，将结果与以往的实验数据进行对比验证模型的有效性。结果建立的肘关节及前臂三维有限元模型与实体解剖标本相似度高，通过模型有效性的验证能准确反映肘关节及前臂的生物力学特性。结论使用有限元法建立肘关节及前臂三维有限元模型进行生物力学研究是可行的。 |

| ObjectiveThis research aims to build the 3D finite element model in elbow joint and forearms for adults.MethodsThe thin slice images between the elbow joint and wrist joints of healthy adults,obtained from CT scanners,are imported to software (eg.Mimics,Hypermesh) in order to build a 3D finite element models of elbow joint and forearms.The constructed model is used to do stress loading experiment,using LS-DYNA for calculation.The final results are compared with former experimental results we got for testifying the validity of the current model.ResultsThe similarity between the constructed 3D finite element model of adult elbow joints and forearms and its corresponding human anatomy specimen is high;the biomechanical properties could be reflected rightly by testifying the model validity.Conclusion It is feasible to analyze orthopaedic biomechanics through the construction of 3D finite element model of adult elbow joint and forearms based on finite element methods. |
