Various loads have a significant effect on the operation of different equipment components. Modern national and international studies show high efficiency of applying finite element methods to research into the loading nature of various parts and systems as a whole. Unevenly distributed loads can reduce the performance of the equipment, as well as lead to the failure of components. This paper examines the effect of the position of the substrate gripper system on the deformations in the printing cylinder. The findings prove that the misalignment of the shaft and gripper bridge placement doubles the resulting deformations.
The paper deals with petroleum road bitumen interacting with the components of a complex modifier. They are high-pressure polyethylene, thermoelastoplast, polymer packaging waste and surfactants. The analysis of changes are presented in the physical and mechanical properties of binders for road pavements obtained by Fourier-IR spectroscopy, optical methods and standard equipment for measuring the qualitative indicators of road binders based on petroleum bitumen.
The vibration of bearings No. 60,206 with radial clearance of 0…0.45 mm is investigated. Analysis of the frequency response (FR) of vibration acceleration reveals information frequencies of 6 Hz, 15 Hz, 26 Hz, and 46 Hz, which coincide with the calculated values. The dependence of the vibration acceleration amplitude on the radial clearance for the specified frequencies is determined. The possibility of rolling bearing wear estimation by vibroacoustic diagnostic methods using artificial neural networks is proved. Diagnostic accuracy with the 4:4-3:1 MI network ranges from 75.6% for a radial clearance of 0.15 mm to 100% for a clearance of 0 mm.
The paper reviews the methods of cleaning plastic parts from flash. The principle of plant operation to obtain L. A. Yutkin electro-hydraulic effect is considered. The design of a pilot plant, as well as replaceable devices used to remove the flash from the edges of plastic parts is presented. The results of experimental studies of the electro-hydraulic effect for deflashing are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
