ABSTRACT
Purpose. Conduct a review and critical analysis of methods for assessing the stress–strain state of rope-capacity split drums in mine hoisting machines and formulate requirements for an integrated modeling methodology for such drums with disc brakes for operation at great depths, based on the criterion of allowable axial deformation of the brake disc.
The methods. It involves systematizing publications and the requirements of the technical specification and forming a consistent set of models: an analytical shell model of the adjustable part, a finite element model, a formulation of topology optimization for the stiffening structure, and a thermomechanical model of the “brake disc–pad” pair. The models are integrated through common interface parameters describing deformability and thermal loading.
Findings. It was found that methods for analyzing the stress–strain state of mine hoisting drums and thermomechanical calculations of disc brakes are mostly applied separately, which reduces the reliability of assessing the brake unit performance for high rope-capacity drums. It is shown that the axial deformability of the drum end faces governs the axial runout of the brake disc and the non-uniformity of contact in the “disc–pad” pair; an engineering performance criterion is proposed, and the structure of an integrated modeling approach is outlined to substantiate design solutions and braking modes.
The originality. An integrated calculation methodology is proposed that combines an analytical shell model, finite element analysis, topology optimization of the stiffening structure, and thermomechanical analysis of the brake unit; the models are coordinated using the criterion of allowable axial deformation of the brake disc.
Practical implementation. The developed requirements and methodology structure provide a calculation-based justification of the parameters of the TsR-6,75×6,2/1,95 drum and its stiffening system under mass constraints, reduce the risk of exceeding geometric tolerances, improve the substantiation of emergency braking modes, and enable assessment of the thermal performance of the “brake disc–pad” pair.
Keywords: mine hoisting machine, split cylindrical drum, increased rope capacity, axial stiffness, finite-element modeling, analytical model, disc brake.
