this survey was done for constructing an egg sorting machine which could sort white eggs from fertilized eggs. egg sorting machine was constructed based on physiological properties of trout egg. fertilized eggs have much more elasticity than white or non-hatched eggs. so the hatched eggs will fly back if were hit to a solid surface. the machine divided to 5 parts including mechanical, electrica...

Anti-Friction Bearing (AFB) is a very important machine component and its unscheduled failure leads to cause of malfunction in wide range of rotating machinery which results in unexpected downtime and economic loss. In this paper, ensemble machine learning techniques are demonstrated for the detection of different AFB faults. Initially, statistical features were extracted from temporal vibratio...

In the article, object of research is development a technology for improving operational properties cast parts from steel 45, obtained by method electroslag remelting. Based on results, modes heat treatment shaft-gear part in an aqueous medium water-oil, to increase service life product, and energy-saving melting remelting were developed. Particular attention paid analytical implementation math...

Tribological properties are determinant in the functionality of contacting surfaces machine elements. The wear resistance or load bearing capacity influence lifetime these parts. In this study tribology-related surface topography parameters (Ssk, Sbi) and hardness hard turned analyzed after measurements. Correlation coefficients were calculated for their relationships. It was found that cutting...
