Abstract:
The article proposes a qualimetric method for assessing the quality of such hazardous production facilities of a metallurgical enterprise as special bridge metallurgical cranes. The supporting structure of the crane is investigated, structurally divided into four main groups of structures and fifteen elements, which carry all the information about the dominant properties of the operation of the crane. Two indicators of the quality of the crane structure were introduced: complex and integral. For a complex function, the probability density function of the reliability levels of structural elemen

The article critically analyzes the standards for assessing the quality of the supporting structures of special bridge metallurgical cranes. At the present stage, more than 80% of such cranes are operated outside the warranty period. The standards are aimed either at a finite number of operating cycles, or at objects of low complexity, in particular FMEA. To estimate the resource, the characteristic number, a generalized indicator of the supporting structure, is used. Risk analysis is a promising and recommended one today.

Electromechanical processes occurring when the load is lifted by an overhead crane are considered. The main idea of the work is to identify emergency mode (crane overload) by a method based on control of stator current of lift motor. To obtain stator current diagrams of electric motor, mathematical model of overhead crane (three-mass circuit) has been developed, which includes equations describing elastic properties of crane beams and its rope. A system of (α, β) coordinates, fixed relative to electric motor stator, is adopted to describe the drive asynchronous motor. Lifting cycle is consider
