摘要/Abstract

摘要： 针对枪托连续冲击作用下人体系统参数随时间变化的特点，提出了一种人体物理参数辨识方法。该方法通过正交化经验模态分解和Hilbert变换构建输入和输出信号的解析信号。通过推导含参数变量的解析信号方程并计算求解获得人体参数随时间的变化曲线。表面肌电实验结果证明了该方法的有效性。辨识结果表明，该方法获得的连续冲击作用下人体等效刚度和等效阻尼参数曲线与生物学知识相符，具有重要意义。

Abstract: A parameter identification method of human body under successive impact is proposed, considering the variation of the parameters over time. Orthogonal empirical mode decomposition (OEMD) and Hilbert transform are used in the method to build the analytic signals of input and output signals. The equation of analytic signals with variable parameters is derived, and the human body parameters changing with time are calculated. Surface electromyography experimental results show that the proposed method is effective. Identification result shows that the equivalent stiffness and equivalent damping parameters of human body under successive impact obtained in this paper are consistent with biology.

Key words: ordnance science and technology, parameter identification, biodynamics, time-varying system, orthogonal empirical mode decomposition, successive impact
