摘要
足底压力可揭示人体在不同状态下的步态运动特性和动力特性,能反应人体的某些运动机能.本文通过建立下肢摆动腿模型,分析步态运动状态下足底压力的形成机理以及步态速度对足底压力带来的影响,为足底压力的应用提供了更充分的理论依据.通过分析运动过程中足底压力的受力情况并进行合理假设,得到下肢摆动腿的简化模型,从而得到步态运动状态下步态速度对足底压力的影响.取步态速度为变量,使用下肢摆动腿简化模型对足底压力受力情况进行仿真实验,并与实际实验进行对比.对比实验证明步态速度与足底压力关系模型与实际相符.
Plantar pressure can reveal the gait movement and the dynamic characteristics of human body in various conditions. In order to analyse the formation mechanism of plantar pressure and the impact of gait speed to plantar pressure,a swinging leg model is presented in this paper, which can supply theoretical support for the applications of plantar pressure. Simplified models of leg swinging can be gotten by analysing stress situations of plantar pressure during activities and making a reasonal assumption. Then the impact of gait speed on plantar pressure can be gotten. Take the gait velocity as variable, and use swinging leg model to do the simulation experiment and laboratory test. The result of emulation accords with the experimental data.
