Abstract

Background. The research object is geometric characteristics of textile products when being formed into the annular layer in a washing drum during the spinning cycle. The subject of the study is assessment of the impact of processes of annular formation of textile products during the spinning cycle on their geometric characteristics, determining the allocation of power factors in the amount of textile products. The purpose of the work is to describe the behavior of the radius-vector of circumferential layers, along which there are centrifugal forces leading to deformation of textile articles in a drum during the spinning cycle with the random nature of their distribution and the maximum unbalance.
Materials and methods. The authors considered the geometry of positions of textile articles in a washing machine drum during the spinning cycle in the polar coordinate system, which allows to determine the magnitude of the radius-vectors of the inner annular layers of the location of textile products.
Results. The authors developed a scheme of conditional distribution of individual annular layers of textile articles in a drum during the spinning cycle and derived formulas determining the value of the radius-vectors of annular layers along which appear centrifugal forces leading to deformation of textiles. The formulas take into account the random nature of the distribution of rings of textile articles in a drum during the spinning cycle. The authors also obtained equations the maximum unbalance of textile products.
Conclusions. The analysis of the distribution of conditional individual annular layers of textiles has showed that unlike the uniform proportional distribution, the coordinates of the center of each layer will be different, which, consequently, determines various values of the coordinates of the center of wringed textile masses. The obtained formulas allow to investigate the behavior of the radius-vector of individual annular layers, as one of the factors determining the centrifugal force, forming a ring of textile products during the spinning cycle.
