Today, energy conservation is a priority. This is due to the shortage of energy resources, the growth of their cost and global environmental problems. The production of compressed air is a wery costly and power-consuming process. One of the areas of energy saving is to improve the quality of the air preparation equipment, in particular, to increase the energy efficiency of this type of devices such as adsorption dryers for compressed air. Reduction of unnecessary energy losses in this sphere is possible due to the use of innovative technologies. The functioning of the adsorption dryer is associated with the consumption of compressed air, which is consumed during the periodic regeneration of the adsorbent. The practical value of the research includes an explanation of the regularity of the influence of the temperature drop, at which the adsorbent regeneration process takes place, on the reduction of the airflow loss during the proceedings of the dryer.
The disadvantage of the geometry of thin-walled parts, in terms of processing, is the low ability to resist static and dynamic loads. It is caused by the elastic deformation of elements with a low stiffness. Modelling approaches for the evaluation of deflections during machining are presented. Mathematical models of deflections, cutting forces and harmonic response are proposed. The processes of material removal and deflection of a thin-walled sample at the critical points are modelled. A frequency analysis was performed, consisting of a modal analysis of natural frequencies and a harmonic response analysis. As a result, a graph of the deflections amplitude from the frequency of driven harmonic oscillations is generated. The analysis of the obtained values was performed. As a result, the resonance frequency and maximum amplitude of oscillations for the operating parameters are determined.
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.
