Frictional contact analysis in a spherical roller bearing
(Oxford University Press, 2023-02)
Numerical analyses of the roller–raceway contact have been carried out in a spherical roller bearing using frictional contact models of different complexity. The models used in the study include an implementation of Kalker’s ...
Drilling Process in γ-TiAl Intermetallic Alloys
(MDPI, 2018-11-26)
Gamma titanium aluminides (gamma-TiAl) present an excellent behavior under high temperature conditions, being a feasible alternative to nickel-based superalloy components in the aeroengine sector. However, considered as a ...
Prediction Methods and Experimental Techniques for Chatter Avoidance in Turning Systems: A Review
(MDPI, 2019-11)
The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for ...
Hole Making by Electrical Discharge Machining (EDM) of -TiAl Intermetallic Alloys
(MDPI, 2018-07)
Due to their excellent strength-to-weight ratio and corrosion and wear resistance, gamma-TiAl alloys are selected for aerospace and automotive applications. Since these materials are difficult to cut and machine by ...
Improving Stability Prediction in Peripheral Milling of Al7075T6
(MDPI, 2018-08)
Chatter is an old enemy to machinists but, even today, is far from being defeated. Current requirements around aerospace components call for stronger and thinner workpieces which are more prone to vibrations. This study ...
Sensitivity Analysis of Tool Wear in Drilling of Titanium Aluminides
(MDPI, 2019-03-06)
In the aerospace industry, a large number of holes need to be drilled to mechanically connect the components of aircraft engines. The working conditions for such components demand a good response of their mechanical ...
Multioperation capacity of parallel manipulators basing on generic kinematic chain approach
(Elsevier, 2017-06-07)
The idea of designing multioperation mechanisms capable of performing different tasks has gained prominence in the last years. These mechanisms, commonly called reconfig- urable mechanisms, have the ability to change their ...
Composite Mould Design with Multiphysics FEM Computations Guidance
(MDPI, 2023-02-17)
Composite moulds constitute an attractive alternative to classical metallic moulds when used for components fabricated by processes such as Resin Transfer Moulding (RTM). However, there are many factors that have to be ...
Latest Developments to Manufacture Metal Matrix Composites and Functionally Graded Materials through AM: A State-of-the-Art Review
(MDPI, 2023-02-20)
Multi-material structure fabrication has the potential to address some critical challenges in today’s industrial paradigm. While conventional manufacturing processes cannot deliver multi-material structures in a single ...
On Constraints and Parasitic Motions of a Tripod Parallel Continuum Manipulator
(MDPI, 2023-01-06)
A parallel continuum manipulator (PCM) is a mechanism of closed-loop morphology with flexible elements such that their deformation contributes to its mobility. Flexible hexapods are six-degrees-of-freedom (DoF) fully ...
