it is shown in the article, that at irrational correlation of internal and elastic parameters of the main lines of rolling mills, the internalresonant phenomena, having a character of fluctuation of oscillations, arise in their transmissions that in their turn stipulate fatigue destructions of the basic parts and units of rolling mills and quality deterioration of the rolled produce. the higher are the speed conditions of the exploited machinery the greater is a negative effect of influence of the internal-resonant phenomena on durability of constructions and quality of the rolled stock. a rolling process in the finishing groups stands of the wire - and thin sheet rolling mills is especially characterized by such operating conditions. W artykule pokazano, że przy irracjonalnej korela[...]
