Dynamic reaction of a human on vibrations by analysis of a single-dimensional biomechanical model
Journal Title: Bulletin of the Military University of Technology - Year 2018, Vol 67, Issue 4
Abstract
The article presents the concepts of the assessment of harmfulness of vibrations generated from various sources. Domestic and foreign standard procedures were discussed, including ISO proposals. It has been pointed out that all procedures can be considered as indirect ones, that they refer to vibrations affecting humans, and not those resulting from the dynamic response induced in individual human organs. The same applies to the criteria for determining the loss of life in communication collisions. It was pointed out that in the literature we find attempts of a direct approach, the essence of which is to study the dynamic reaction of individual human organs inscribed in the one or twodimensional model. The results of own tests of a person subjected to intensive oscillatory procedures were presented in order to identify the stiffness model proposed to assess the harmfulness of industrial type vibrations. It has been shown that two-dimensional models can be suitable here. Keywords: harmful effect of vibrations, human biomechanical models, one-dimensional model C.M. Harris, model identification, differential solution.<br/><br/>
