Abstract An academic model for passive vibration control of human arm suffering from essential tremors is proposed. The nonlinear uncontrolled system equations are linearised around arbitrary postural positions showing variations of linear natural frequencies as functions of postural positions. The coupled system, i.e. the model of the arm with the attached nonlinear absorber, is treated via a time multiple scale method leading to detection of fast and slow systems dynamics. These dynamics provide design tools for tuning parameters of the nonlinear absorber.

人体手臂的非线性被动震颤控制

摘要 提出了一种用于特发性震颤的人体手臂被动振动控制的学术模型。非线性不受控制的系统方程围绕任意姿势位置线性化，显示线性自然频率的变化作为姿势位置的函数。耦合系统，即带有附加非线性吸收器的臂模型，通过时间多尺度方法进行处理，从而检测快速和慢速系统动力学。这些动力学为调整非线性吸收器的参数提供了设计工具。
