摘　　要：基于CT扫描切片,利用商业软件构建了包含韧带及软组织等组成的骨盆三维有限元模型;采用非线性六面体单元对其进行了网格划分和优化,以保证计算结果的精度和准确性。通过分析骨盆站位时的受力工况,给出了力的传递路径,验证了所建模型的有效性。研究发现,该模型能够基本反映站位时人的生理状态,可为临床分析研究提供技术指导。On the basis of the CT scan slice, three-dimensional finite element model of the pelvis containing ligaments and soft tissue was built using the commercial software. To ensure the accuracy of the calculated results, the nonlinear hexahedron elements were used to conduct grid division and optimization. By analyzing the stress condition with the pelvis standing, the paper gives the force transfer path, verifies the effectiveness of the model. The results show that the model precisely represents the physiological state of the pelvis standing,and can be used to pro-vide technical guidance for clinical research.
