STAND FOR EXPERIMENTAL RESEARCH OF THE IMPACT OF LOCAL VIBRATIONS ON HUMAN

It is known that the vibration disease takes the leading place among occupational diseases and has quite a polymorphic clinical symptomatology. An in-depth study of the pathogenesis of vibration disease to identify signs of neurovascular, neurohumoral and trophic disorders at the prenosological stage requires an integrated biomedical and biophysical studies the effects of vibration in standardized conditions. Only in a laboratory experiment can be simulated and repeatedly play the identical fully researched vibration modes and its combined effects with various other harmful for the body. The aim of the study is the principle of constructing the stand for modeling local vibration, which, with simplicity of its realization, allows you to create a simulated workplace conditions as close as possible to the practical production the process of using standard hand tools with built-in motor. Material and methods. Stand mount according to the tasks of ensuring the necessary to simulate vibration poses human operator regarding the working Panel. As vibrogenerator choose the corresponding technical characteristics standard hand tools with built-in motor (drill, punch, etc.), in a cartridge which embody the work item. Vibration sensors lock on is selected for the study areas of the body and connect to the input of the measuring instrument. Vibration load sensors are fixed on the selected areas of the body and connected to the input of the measuring device. Results. The presented measurement results have a very small scatter of parameters between operators (men and women), which indicates the absence of significant deviations of the spin axis, the center rod, from the axis of the recess in the working panel and the identity of the load on the vibration tool created by the operators. Discussion. By the approbation results the offered stand allows to reproduce conditions of a workplace and a working pose of the operator, as much as possible approached to practical production of works. Approbation of the stand clearly showed the simplicity of modeling local vibration under identical experimental conditions for all operators. Conclusions. The stand can be used for scientific research in the field of occupational medicine and industrial ecology, as well as in the educational process for laboratory work.
