【摘要】：目的研究一種高質量、高效率的骨骼分網(wǎng)方式。方法結合骨結構的特點,將流體動力學(computational fluid dynamics,CFD)的分網(wǎng)方法引入到骨生物力學的網(wǎng)格劃分中,用六面體單元模擬皮質骨,四面體單元模擬松質骨。結果采用CFD網(wǎng)格劃分技術能夠劃分出高質量的六面體單元,并且較好地模擬骨骼的結構特征,可以實現(xiàn)計算機自動分網(wǎng),分網(wǎng)花費時間約為傳統(tǒng)分網(wǎng)方法的1/5,有限元模型計算結果基本符合尸體實驗測量值。結論CFD網(wǎng)格劃分技術可應用于骨生物力學領域中,為復雜人體骨骼的重構探索了一條有效途徑。
[Abstract]:Objective to study a high-quality and high-efficiency bone separation method. Methods according to the characteristics of bone structure, the method of hydrodynamic (computational fluid dynamics,CFD was introduced into the meshing of bone biomechanics. The hexahedron unit was used to simulate the cortical bone and the tetrahedron unit to simulate the cancellous bone. Results the high quality hexahedron unit can be divided by using CFD mesh division technique, and the structural characteristics of bone can be simulated well, and the computer automatic network division can be realized. The time of the subnet is about 1 / 5 of that of the traditional method, and the calculated results of the finite element model are basically in accordance with the measured values of the cadaver experiment. Conclusion CFD mesh generation technique can be used in bone biomechanics and provides an effective approach for the reconstruction of complex human bones.
