MAQOLA ANNOTATSIYASI

In this article, a physical and mathematical model of the external forces involved in reducing the static loading of the body of workers and people using video terminals or computer monitors in a sitting position was developed. A theoretical analysis was conducted on the basis of the developed models, the equations of the balance conditions of the forces in the physical model made it possible to create a mathematical model. Through the analysis of the created mathematical model, the conditions for the minimum contraction force of the members of the human locomotor apparatus, that is, the muscles participating in the maintenance of the posture of the workers and people during the work process in the sitting position, were determined. The conditions obtained on the basis of the defined mathematical model are used in the development of the model of the course layout, which allows to ensure the "neutral position" of the human body, and to calculate the values of the project parameters.
