顺应性是人类运动的一个重要特征，许多研究都集中在刚度参数的识别上，以构建新的机器，并且刚度通常被假设为恒定的。然而，研究表明，在人类行走过程中，刚度分布并不是随时间恒定的，并且具有高调制，特别是在改变行走阶段时。为了了解恒定刚度假设如何影响步行步态以及步行机制需要多少调制才能再现自然步态，在这项工作中，我们重点分析关节和双关节刚度分布调制以及这些调制对不同步行环境（即平地、斜坡和楼梯）中行走运动的影响。该分析是根据运动捕捉数据的周期性步骤进行的。映射到带有弹簧阻尼系统的 14 节人体模型上。
Compliance is an important feature of human locomotion, where many studies have focused on the identification of stiffness parameters in order to build new machines, and stiffness is often assumed to be constant. However, it has been shown that during human walking, stiffness profiles are not constant in time and have high modulations in particular when changing walking phases. In order to understand how the constant stiffness assumption influences the walking gait and how much modulation is needed in walking mechanisms to reproduce natural gaits, in this work we focus on the analysis of joint and bi-articular stiffness profiles modulation and the influence of these modulations on the walking motions in different walking environments, i.e. level ground, slope and stairs. The analysis is carried out on periodic steps from motion capture data. mapped on a 14 segments human model with spring damper systems.
