Parameter Identification of Human Body under Successive Impact

doi:10.3969/j.issn.1000-1093.2016.04.004

Abstract

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
