Load of frontal surface rope drum

Abstract

In the article one considers questions of strained condition of the frontal surface of a rope drum. All methods of calculations of a frontal surface rope drum have many defects, main in this are – not calculation variable of load wail drum from compression of spin rope, coefficient of friction, geometrical and elastic property of rope and drum. The frontal surface is considered as round plate, this load is on outward circumference outward compression. For calculation supply the problem set function of outward load frontal surface drum and makes up equation of full potential energy plate on unit of length along radius uncalculation deformation displacement. By this one receives equation fourth degree. After decision this function one receives dependence for define deformation the frontal surface of a rope drum under action rope which winds on casing drum. This gives possibility for conducting calculations of a load of frontal surface and value necessary strengthening her elements of hard.
