Results of an experimental study on crushing granite from Iset deposit of the Ural region on the SHD-10M jaw crusher has been presented. Degree of influence of a bearing assembly of the SHD 10M crusher on fineness of final product by fractions has been determined, experiments with sampling has been conducted, results has been recorded, fineness characteristics of crushing product by “plus” and “minus” using the A-20 analyzer has been determined. Values of productivity, crushing time by fineness classes has been given.

Introduction. The article considers the calculation of the strength of a bearing mounted on the connecting rod of a jaw crusher, taking into account all workloads. ISSN 0536-1028 «Известия вузов. Горный журнал», № 3, 2020 117 Object problems. When creating particularly large machines and systems, in the case of their 3D-modeling and detailed study, we are faced with an increased load on the central processor of the computer, as well as on the graphics and RAM modules, which leads to a significant slowdown in the design process and calculations particular. Research aim is to consider the task of selecting a simpler and "easier" for the calculation model programs, not difficult to parameterize, compared with the original bearing model, but providing accuracy in the calculation in an acceptable range of errors. The research also aims to analyze the stress-strain state of the bearing assembly. The main methods. In the calculations, the finite element method was used. Specialized software package APM WinMachine was also used. Computing experiment conducted. Conclusions. The results of a computational experiment satisfy the requirements and can be used to solve further problems of designing bearing assemblies. In the future, a parameter-dependent model can be created to facilitate the calculation using any type of bearing

The change in the static stiffness of a bearing assembly is an important discriminator when determining the size of a defect in a rolling element bearing. In this article, the force–displacement relationships for defective bearings under various static radial loadings at various cage angular positions are analytically estimated and experimentally measured and analyzed. The study shows that the applied load has a significant effect on the static stiffness variations in defective rolling element bearings. The experimental measurements of the effect of the defect size on the varying stiffness of the bearing assembly, which has not been shown previously, provides valuable knowledge for developing methods to distinguish between defective bearings with defects that are smaller or larger than one angular ball spacing. The methods and results presented here contribute to the wider experimental investigation of the effects of loadings on the varying static stiffness of defective bearings and its effects on the measured vibration signatures. A large data set was obtained and has been made publicly available.

Abstract A nonlinear, numerical model of a dry, compressible atmosphere is used to simulate the hydrostatic and geostrophic adjustment to a localized prescribed injection of momentum applied over 5 min. with a size characteristic of an isolated, deep, cumulus cloud. This theoretical study is relevant to the initialization of updrafts in compressible numerical weather prediction models. The four different forcings studied are vertical, divergent horizontal, and nondivergent horizontal momentum forcings, and a prescribed transverse circulation. These forcings are applied to an isothermal atmosphere, a nonisothermal atmosphere, and an atmosphere with a nonisothermal troposphere capped by an isothermal stratosphere. These scenarios are studied by analyzing the resulting perturbation fields and the energetics of the system. Potential vorticity is used to determine the possibility of steady atmospheric states. The energetics of the system are examined to observe the creation and propagation of atmospheric waves. Both traditional and available energetics are used to determine the presence and strength of these waves. Traditional energetics consist of kinetic, internal, and potential energies while available energetics consist of kinetic, available potential, and available elastic energies. The efficiencies are similar for these different energetics, though they represent different phenomena. The traditional energetics show a strong dependence on the presence of a Lamb wave, whereas in the available energetics the Lamb wave has little or no effect.
