Predictions of friction coefficient in hydrodynamic journal bearing using artificial neural networks
Dragan Milčić, Amir Alsammarraie, Miloš Madić, Vladislav Krstić, Miodrag Milčić
Izvirni znanstveni članek
Oznake: artificial neural network;hydrodynamic journal bearing;babbitt metal tin-based alloy;friction coefficient;
This paper explores the influence of the frequency of shaft sleeve rotation and radial load on a journal bearing made of tin-babbitt alloy (Tegotenax V840) under hydrodynamic lubrication conditions. An experimental test of the frictional behaviour of a radial plain bearing was performed on an origin ...

Oznake: directed energy deposition;DED;wire and arc additive manufacturing;WAAM;in-situ vibrations;heat treatment;porosity reduction;residual stress;grain refinement;surface waviness;mechanical properties;fracture toughness;computed tomography scan;CT;
Directed Energy Deposition (DED) processes offer the advantage of producing larger parts with higher deposition rates compared to Powder Bed Fusion (PBF) additive manufacturing (AM). However, DED typically results in simpler geometries and lower resolution. When using Wire and Arc-based DED, even ...
