Human shank experimental investigation and computer simulation

摘要

A new combined approach to analyse a physiological state of the human shank is developed. Investigated vibration research complex records resonance curve of the shank tissues automatically for different kinds of vibration excitation and for various positions of the foot. A special computer model is implemented for the estimation of the experimental data, for a priori prognosis of the bio-object behaviour and its dynamic characteristics in the case of various kinds and of different degrees of injury. The model is described by the viscous-elasticity non-homogeneous one-dimensional continuum equation. It is solved by finite element method. The problem in shank cross-section is solved by boundary element method. The analysis of computer simulated resonance curves makes it possible to understand the experimental data correctly and to check the diagnostic criteria of the injury.
