(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper discusses the results of the investigation of occurrence of cracks in the structure of bucket wheel excavator (BWE) slewing platform, the repair procedure and the reconstruction of the slewing platform. The ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...
Research of rail traction shafts and axles fractures towards impact of service conditions and fatigue damage accumulation
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Traction shafts and axles of railway vehicles are designed to be safe and reliable in normal service conditions Accidental and unpredictable conditions including bad exploitation (rail tracks, maintenance and extreme long ...
Investigation of causes of fan shaft failure
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Energy efficiency of thermal power plants depends on the vital plant elements' reliability levels. In order to preserve high level of energy efficiency, the vital elements' operational capability is continually monitored ...
Calculated and experimental analysis of cause of the appearance of cracks in the running bogie frame of diesel multiple units of Serbian railways
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this paper an analysis of possible causes of crack occurrence on reconstructed diesel multiple units (DMU) exploited on sideline in Serbia was performed. Analyzed DMU were designed in the sixties of the last century in ...
Condition and behaviour diagnostics of drive groups on belt conveyors
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Belt conveyors are complex systems with drive groups as functionally very important components. Their proper and reliable operational life is directly related to durability of the load-bearing steel structures. Drive units ...
FEM based fatigue crack growth predictions for spar of light aircraft under variable amplitude loading
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In the last decades, the assessment of the service durability of aerospace components and assemblies has become an important segment of design, mostly because of the growing needs for the light-weight structures which will ...
Technological heredity - A decisive factor for tribological features of regenerated gears
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The reparatory hardfacing of damaged contact surfaces is the most reliable method of renewing the tooth shape, dimensions and operating characteristics of failed gears. Proper selection of method suitable for reparatory ...
Analysis of the spreader track wheels premature damages
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The superstructure of the ARs 2000 spreader leans on three crawlers of identical length, width and height. Serious damage to the track wheels threads occurred already during the spreader's travel from the erection site to ...
