本研究模型中韧带模型结合解剖学及影像学资料确定韧带在足部的附着点和走向，在附着点处提取节点，连接两节点生成模拟足底韧带的单元。本研究的韧带使用 ANSYS WORKBENCH 20 R2（美国，Ansys 公司）软件建立。足底韧带根据解剖图谱确定韧带的起止点，韧带使用弹簧单元建立，主要弹簧韧带刚度选自参考文献。

In this research model, the ligament model combines anatomical and imaging data to determine the attachment point and direction of the ligament in the foot, extract nodes at the attachment point, and connect the two nodes to generate a unit simulating the plantar ligament. The ligaments in this study were established using ANSYS WORKBENCH 20 R2 (Ansys, USA) software. The plantar ligament determines the starting and ending points of the ligament according to the anatomical atlas. The ligament is built using spring elements. The main spring ligament stiffness is selected from the references.
