摘要
结合 CT& MRI数据 ,提出了一个构造完整人体下肢肌肉 -骨骼拓扑模型的方法。给出了人体下肢 14块肌肉的拓扑结构和各肌肉的起止点坐标。基于肌肉的拓扑结构 ,分别建立了肌肉的直线模型和质心模型。同时在所构造的模型基础上 ,对肌肉力预测方法进行了分析 ,提出了基于步态平衡的肌肉力多目标优化方法 ,对进行人工关节的设计和其后的 CAE分析具有重要意义。
A new method to reconstruct comparatively complete muscle model of human lower limb from CT and MRI data is presented. Topological structure of more than fourteen muscles is built and the coordinates of origin and insertion points are given. Based on this model, straight-line model and centroid-line muscle model are acquired. Muscle force prediction is discussed according to the model reconstructed, and a multi-objective optimization method is put forward for evaluating muscle forces of human lower extremity.
