使用ANSYS WORKBENCH 20 R2软件的准静态分析,在对模型前处理完成之后,开始进行加载求解等相关设置,主要包括施加载荷和约束,设置求解项等,具体加载方式如下:首先,设置约束载荷,约束胫腓骨上平面前后、左右、上下的位移;其次,加载跟腱力 ,跟腱力为足部承受载荷的50%。站立时垂直方向地面反作用力为体重的1倍,所以本次研究右足的地面反作用力设置为体重的一半,为320N,跟腱力即为160N;最后,加载位移载荷,地面反作用力通过冰面垂直向上运动,经过多次试验,找到冰面向上运动达到地面反作用力(320N)的具体距离,同时约束冰面的水平和前后方向。冰刀和地面之间的摩擦系数为 0.6。
Using the quasi-static analysis of ANSYS WORKBENCH 20 R2 software, after the pre-processing of the model is completed, the relevant settings such as load solution are started, mainly including the application of loads and constraints, and the setting of solution items. The specific loading method is as follows: first, set the constraint load to constrain the front and rear, left and right, up and down displacement of the upper plane of the tibia and fibula; Secondly, load the Achilles tendon force, which is 50% of the load on the foot. When standing, the vertical ground reaction force is one time of the body weight, so the ground reaction force of the right foot in this study is set to be half of the body weight, 320N, and the Achilles tendon force is 160N; Finally, load the displacement load, and the ground reaction force moves vertically upward through the ice surface. After many tests, find the specific distance between the ice surface moving upward and the ground reaction force (320N), and constrain the horizontal and front and rear directions of the ice surface. The friction coefficient between the ice skate and the ground is 0.6.
