利用ANSYS WORKBENCH 20 R2软件，将刀托和冰刀设为绑定（Bonded）接触。绑定接触的使用条件是若一对接触对的接触状态对整个模型影响不大，或这一接触对在整个分析过程中始终紧密接触，就可以将它们的关系定义为绑定接触。由于冰刀和速滑鞋在运动过程中也是紧密接触，所以本研究将刀托和冰刀的接触定义为面-面的“Bonded”接触，这种接触是一种既无分离也无滑动的接触方式，在接触面或接触边之间不存在法向的相对分离或切向的相对滑动。

Use the ANSYS WORKBENCH 20 R2 software to set the knife holder and the ice skate as bonded contact. The use condition of binding contact is that if the contact state of a pair of contact pairs has little impact on the whole model, or if the contact pairs are always in close contact during the whole analysis process, their relationship can be defined as binding contact. Because skates and speed skates are also in close contact in the process of movement, the contact between the skate holder and skates is defined as face-to-face "bonded" contact in this study. This contact is a contact mode without separation or sliding. There is no normal relative separation or tangential relative sliding between the contact surface or the contact edge.
