“…To identify the most loaded sections of the crusher drive shaft, a static analysis and strength analysis were performed using Autodesk Inventor 2020 software. Strength criterion is one of the most significant operability criterion of machine parts [30][31][32][33][34][35][36][37][38][39][40].…”

The paper analyzes the causes of failures of coarse crushers “KKD 1500-180” at JSC “Almalyk MMC”. It has been established that the most common cause of these failures is a drive shaft failure. Static analysis of the strength of the drive shaft was performed using Autodesk Inventor 2020 CAD software. A dangerous shaft section was found, and recommendations aimed at improving its operability were proposed.

“…The third theory [18][19][20] explains surfaces refining process by abrasive grains as purely thermal, i.e. due to friction of abrasive on the surface to be processed temperature of the surface layer increases significantly which makes the surface layer liquefy and due to the surface tension forces 'troughs' are filled with 'protrusions' forming smooth surface and instantly solidified layer.…”

The paper presents experimental studies on physical and chemical processes that occur as a result of refining by ‘GOI’ paste (description in CIS countries, it states for State Optical Institute) largesized precision details made from non-ferrous metals.Number of hypotheses expressed by number of scientists is compared.Their essence has been revealed and a hypothesis has been adopted and confirmed by Corresponding profilograms and photographs. It is most relevant to process of refining by ‘GOI’ paste of precision contacting inserts made from nonferrous metals. This is very important for agricultural engineering.

Purpose of this paper is to improve parameters of metal structures elements of hoisting-and-transport machines (HTMs) by means of systematic approach to study changes of their stress-strain state during design or usage stage. Subject of the study is pattern of changes in distribution and values of stresses in elements of metal structures of HTMs depending on the structural and parametric characteristics. Design methodology of metal structures of HTMs on the basis of a portal crane is proposed, it is based on strength calculations using methods of allowable stresses and FEM, 3D computer simulation, system analysis of the stress-strain state and structural-parametric synthesis. Results of modeling of loading state and calculations of the portal crane metal structures on strength by FEM in CAD/CAE system, analysis of their stress-strain state, structural-parametric synthesis are presented. Recommendations on practical application of the results are given. Possible ways of further development of proposed solutions are identified.
