Cracks, repair and reconstruction of bucket wheel excavator slewing platform
(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 ...
Desktop 3-axis parallel kinematic milling machine
(Springer London Ltd, Artington, 2010)
Parallel kinematic machines (PKM) are still a research-and-development topic in many laboratories although many of them, unfortunately, have no PKM at all. Therefore, the use of a desktop educational 3-axis parallel kinematic ...
Magnetic Force Microscopy Application in Steel Structure and Milling Process Parameters Evaluation
(Taylor & Francis Inc, Philadelphia, 2009)
Application of scanning probe microscopy techniques in evaluating process quality is presented. We conducted a surface characterization and comparison of topographical and magnetic features for three steel plate samples ...
Development and validation of a new universal through flow method for axial compressors
(Sage Publications Ltd, London, 2010)
This article describes the development of a new through flow method for the analysis of axial multi-stage compressors. The method is based on a stream function approach and a finite-element solution procedure. It includes ...
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 ...
Measurements and analysis of electron transport coefficients obtained by a pulsed Townsend technique
(IOP Publishing Ltd, Bristol, 2010)
A review of a wide range of electron swarm studies in several pure gases and gas mixtures is given. These studies include the determination of the cross section set for electrons in C(2)H(2)F(2) (R134a) based on recent ...
Inhibitory Effect of Cerium Salts of Lower Carboxylic Acids on Al-Zn-Mg-Cu Alloy in NaCl Solution
(Electrochemical Soc Inc, Pennington, 2021)
The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition ...
Surface characterisation of PLLA polymer in HAp/PLLA biocomposite material by means of nanoindentation and artificial neural networks
(Taylor & Francis Ltd, Abingdon, 2010)
In this paper, the mechanical properties of polymer matrix phase (modulus of elasticity, yield stress and work hardening rate) have been determined using combined methods such as nanoindentation, finite element modelling ...
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 ...
