Theoretical analysis and finite element method were used to simulate the cold nosing process of commercial purity Aluminum tubes into conical hemispherical dies. The influences parameters, namely initial tube wall thickness, semi-die angle coefficient friction investigated. results obtained in terms load-displacement curves, thickness distribution deformed parts, ratios strain distributions. Ac...
The influence of the improvement finned tube radiator unit structure on fluid flow and heat transfer effect locomotive was studied. A saw-toothed fin with aluminum instead copper proposed to keep position size flat hot water pipe unchanged. CFD simulation analysis carried out by ICEPAK17.0, under conditions an ambient temperature 24.6 °C, atmospheric pressure 85,040 Pa air density ? = 0.94 kg/m...
This paper shows an influence of chemical composition of used electrolyte, such as amount of sulphuric acid in electrolyte, amount of aluminium cations in electrolyte and amount of oxalic acid in electrolyte, and operating parameters of process of anodic oxidation of aluminium such as the temperature of electrolyte, anodizing time, and voltage applied during anodizing process. The paper shows t...
