Semi-Active Magnetorheological Damper Device for Chatter Mitigation during Milling of Thin-Floor Components
(MDPI, 2020-07-31)
The productivity during the machining of thin-floor components is limited due to unstable vibrations, which lead to poor surface quality and part rejection at the last stage of the manufacturing process. In this article, ...
Uncharted Stable Peninsula for Multivariable Milling Tools by High-Order Homotopy Perturbation Method
(MDPI, 2020-11-06)
In this work, a new method for solving a delay differential equation (DDE) with multiple delays is presented by using second- and third-order polynomials to approximate the delayed terms using the enhanced homotopy ...
Estimation of the Heat Loss Coefficient of Two Occupied Residential Buildings through an Average Method
(MDPI, 2020-11-02)
The existing performance gap between the design and the real energy consumption of a building could have three main origins: the occupants’ behaviour, the performance of the energy systems and the performance of the building ...
Analysis of the dressing process using stationary dressing tools
(Elsevier, 2017)
Grinding process is a very important process in machining industry to manufacture high quality part. The correct preparation of grinding wheel involves dressing process taking importance to optimize grinding process. Due ...
Machining Stresses and Initial Geometry on Bulk Residual Stresses Characterization by On-Machine Layer Removal
(MDPI, 2020-03-22)
Prediction and control of machining distortion is a primary concern when manufacturing monolithic components due to the high scrap and rework costs involved. Bulk residual stresses, which vary from blank to blank, are a ...
A reliable turning process by the early use of a deep simulation model at several manufacturing stages
(MDPI, 2017-05-02)
The future of machine tools will be dominated by highly flexible and interconnected systems, in order to achieve the required productivity, accuracy, and reliability. Nowadays, distortion and vibration problems are easily ...
Five MegawattWind Turbine Power Output Improvements by Passive Flow Control Devices
(MDPI, 2017-06)
The effects of two types of flow control devices, vortex generators (VGs) and Gurney flaps (GFs), on the power output performance of a multi-megawatt horizontal axis wind turbine is presented. To that end, an improved blade ...
On the influence of conformity on wheel–rail rolling contact mechanics
(Elsevier, 2016-07)
The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions.
For this ...
A contact mechanics study of 3D frictional conformal contact
(Elsevier, 2018-03)
A contact mechanics study of three-dimensional conformal contact with friction is presented, based on numerical calculations with Finite Element models and an extension of Kalker's exact contact theory which takes into ...
Dynamic comparison of different types of slab tracks and ballasted track using a flexible track model
(Sage Publications, 2011-11)
The dynamic performance of a ballasted track and three types of slab tracks is analysed and compared by means of a comprehensive dynamic model of the train-track system, generated using two commercial analysis software ...
