Abstract:

Purpose. To develop the method of construction of a generalized parametric model of drum shell of a mining hoist based on its representation as a system with spatially lumped and distributed parameters.

Methodology. The developed method supposes that the object is described by a simplified model with experimentally defined coefficients which allow experimental and computational data to conform well.

Findings. The semiempirical method has been developed. According to it for calculation of bending of shaped shell of hoist drum an analytical model of an axisymmetric shell with equivalent mechanical properties involving coefficients of agreement with the empirical data should be used.

Originality. Dependence of the average flexural rigidity on the geometric parameters of the shell taking into account the reduction coefficient of rigidity has been established.

Practical value. The developed method allows reasonable selection of the parameters of the hoist drum, and its application in the design will create a competitive global market of lifting equipment with reduced weight, increased strength and durability. In comparison with previously used, this method several times will reduce the complexity of calculations of the strength of cylindrical drum winders.
