Abstract

Background. The object of study is the liquid autobalancing device of passive type drum washing machines. The subject of research are the processes and conditions for balancing unbalanced masses of the textile articles at a centrifugal spinning in washing machines with a horizontal rest axis of rotation. The aim of this work is to define the conditions, the implementation of which allows to provide balancing of unbalanced masses in the period of centrifugal extraction throughout the range of frequencies of rotation of the drum.
Materials and methods. Consider question the formation of unbalanced and balance forces in a washing drum with autobalancer device, and the factors that determine the asymptotics of input power impact power response of the system, which allows to determine the conditions necessary for complete balancing of the unbalanced masses of the drum during the spin cycle.
Results. Investigated the factors that determine the asymptotics of input power impact power response of the system under consideration, the formulas for determining unbalanced and balances, as well as the parameters describing the processes of their formation. Describes the conditions under which a possible implementation of the full balance the unbalanced mass of the drum during the spin cycle.
Conclusions. The use of elastic elements autobalancing device with a constant stiffness does not provide a complete trim system. It is shown that as the primary source parameter in the calculation of power factors respective to conditions of equilibration of the system is to move the internal capacity autobalancing device. Found that to ensure complete balancing of the unbalanced mass of the drum in the pressing process requires the use of elastic elements autobalancing device with a nonlinear exponential characteristic quadratic (a parabola of the second order).
