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 ...
SEM and EDS Characterisation of Layering TiOx Growth onto the Cutting Tool Surface in Hard Drilling Processes of Ti-Al-V Alloys
(Hindawi Publishing Corporation, 2011)
Scanning electron microscopy (SEM) has been used to identify and analyse the secondary adhesion effect precursors formed during the dry drilling processes of Ti-6Al-4V alloy over the rake face and flute of the drilling ...
Modelling rail corrugation with specific track parameters focusing on ballasted track and slab track
(Taylor & Francis, 2011-11)
The objective of this paper is to compare 3 types of track (high performance ballasted track, STEDEF and AFTRAV) from the corrugation growth point of view. This work has considered different vehicle speeds and track ...
Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
