| 摘 要： | 为探究跑步运动时女性下肢肌肉、皮肤形变与服装运动功能性之间的关系，通过生物力学仿真系统对周期跑步运动人体下肢肌肉的肌纤维主动力进行分析，选取肌纤维主动力均值明显的肌肉，将其峰值所在的时间帧对应的动作作为关键帧动作，并使用手持式三维扫描仪对关键帧动作的下肢皮肤进行扫描；综合左右半身的皮肤形变情况，分析不同动作的下肢皮肤形变数据差异性，同时对比动静态人体模型展开的细分曲面。研究发现：臀围到中腿围区域的体后侧、臀围至大腿围区域的体前侧的变化幅度最大，膝关节附近区域变化幅度较大，其它区域变化不明显。本文研究可为相关裤装结构设计与研究提供参考。

| Abstract: | Objective Skin deformation refers to the range of skin change measured when key body parts are in motion, including the value of skin surface change rate and the difference between each movement change rates. Obtaining the rules of skin deformation of different parts, which is in the subdivision curved surface of the static and dynamic model of running lower limbs, is to solve the design requirements of the clothing pattern design of running tight functional clothing. A reference is provided for the running pants, and also for design and improvement of related pants pattern. |
