| 摘 要： | 为探索生物骨骼系统三维CAD实体模型的高效快速重建方法,以人体下肢骨骼系统为研究对象,综合运用三种建模思路建立了基于解剖学的精细三维实体模型。该模型表面光滑,曲线流畅,满足后续有限元分析要求。对三种建模方法进行比较分析表明,采用Solid-works、Rhinoceros重建的骨骼具有简单控制线,整体较佳,Geomagic环境下的建模效率较高,且对于具有复杂曲面特征的骨骼或组织快速重建更有效。

| Abstract: | In order to explore the effective method used for the three dimensional solid model constructing of biological skeleton system,the human lower limb skeleton system was employed.Based on three proposed methods,a fine three dimensional solid model of human lower limb skeleton was built successfully in final,which has accurate anatomical topology configuration and could meet the requirements of finite element analysis.Meantime,the comparison and analysis among these three methods showed,the bone CAD model built by either Soliworks or Rhinoceros software package has characteristics of simple control line and higher quality;while in Geomagic environment,the model constructing has more efficiency,especially for processing more complex surface feature based bones. |
