Maintenance decision-making process for a multi-component production unit using output-based maintenance technique: A case study for non-repairable two serial components' unit
(RAMS Consultants, 2013-05)
This paper presents the maintenance decision-making process for the case of a multi-component unit based on output-based maintenance (OBM) technique. OBM is an innovative maintenance technique that applies condition based ...
A method for assessing productivity in unbuffered assembly processes
(Emerald Group Publishing Limited, 2013)
Purpose – The purpose of this paper is to study and perform a system analysis of car assembly line processes, to show productivity losses and their causes, and to derive a mathematical model of the productivity rate of the ...
Yttria stabilized zirconia formed by micro ceramic injection molding: Rheological properties and debinding effects on the sintered part
(Elsevier, 2013-04)
Micro Ceramic Injection Molding (μCIM) is a near net-shape process to produce smaller and intricate parts at a competitive cost. The application of nano-sized ceramic powder in μCIM has the advantages of fine grain size ...
Comparison between single and multi gates for minimization of warpage using taguchi method in injection molding process for ABS material
(Trans Tech Publications, 2013-12)
In this study, a mold is designed in single and dual type of gate in order to investigate the deflection of warpage for thick component in injection molding process. Autodesk Moldflow Insight software was used as a medium ...
Convergence of finite element model for crushing of a conical thin-walled tube
(Elsevier B.V., 2013)
In this paper, a convergence of finite element model using different types and sizes of mesh modes has been conducted. A thin-walled conical tube was modeled using plane shell element in LS-DYNA software under dynamic axial ...
Effect of heat treatment on microstructure and corrosion behavior of Az91d magnesium alloy
(Trans Tech Publications, 2013)
An AZ91D ingot in the as-cast condition was homogenized by heat treatment process. Then, the microstructures produced and corrosion behaviour after heat treatment was studied in detail. As-cast AZ91D was recrystallize by ...
Investigation of the velocity profiles in a ninety-degree curved standing wave resonator with Particle Image Velocimetry
(Trans Tech Publications (TTP), 2013)
Travelling wave thermoacoustic heat engines have been reported to have a higher efficiency than the standing wave ones. The former are generally large systems which consist of toroidal shape resonators. While standing wave ...
Characteristics of Fe-yttria composites fabricated by powder metallurgy method
(Trans Tech Publications, 2013)
This study is focused on fabricating and characterizing iron (Fe) composites prepared by powder metallurgy route reinforced with varying weight of Yttria (Y2O3). Composites were prepared based on 5 wt. % to 15 wt. % of ...
Orthogonal least squares method and its application to nonlinear modeling of automotive engine fuelled with palm oil methyl esters
(Praise Worthy Prize S.r.l., 2013)
In this paper, nonlinear mathematical models for an automotive engine fuelled with palm biodiesel (Palm Oil Methyl Ester) are developed. Assuming a discrete time form for the system model, a polynomial Nonlinear Autoregressive ...
Understanding the behaviour of pulsed laser dry and wet micromachining processes by multi-phase smoothed particle hydrodynamics (SPH) modelling
(IOP Publishing, 2013-03)
A smoothed particle hydrodynamics (SPH) numerical model is developed to simulate the three-phase laser micro-machining process for medical coronary stent manufacture. The open-source code SPHysics is used to model the ...
