Non-destructive experimental technique to determine ball contact load in rolling machine elements
(Elsevier, 2024)
Rolling machine elements, such as ball bearings, ball screws, or guiding systems are commonly used in diverse industrial applications. These components typically assume uniform load distribution among the balls or rely on ...
A general kinematic model for lubricated ball bearings based on the minimum energy hypothesis
(Elsevier, 2024)
Accurately predicting the performance of lubricated rolling elements is critical for certain key bearing applications. A widely employed simulation technique is quasi-static models, which although computationally efficient ...
Definition of 3D Printing Parameters by the Design of Experiments to Characterise Carbon Fibre-Reinforced Polyamide
(Springer, 2024)
This paper presents the application of an advanced quality management tool, the design of experiments (DOE), in order to characterise a new material (carbon fibre-reinforced polyamide) used in the 3D printing process. The ...
Combining experimental and FEM approaches to determine the influence of workpiece temperature on fundamental variables in the machining process
(Materials Research Forum LLC, 2024)
In machining it is common practice to use lubricants to enhance machinability, resulting in improved part quality and reduced tool wear. However, emerging efforts are centered on mitigating the environmental impact of ...
Gallium Nitride Power Devices: A State of the Art Review
(IEEE, 2023)
Wide Bandgap (WBG) semiconductor materials present promising electrical and thermal characteristics for Power Electronics applications. These WBG devices make it possible the development of more efficient converters with ...
Simple and Affordable Method for Fast Transient Measurements of SiC Devices
(IEEE, 2020)
The measurement of fast voltage and current transients of Silicon Carbide (SiC) devices requires high bandwidth (BW) probes. Commercially available voltage and current probes can be expensive, and, in addition, the delay ...
Análisis del efecto de shot-peening y el cementado en la vida a fatiga de los engranajes
(Sociedad Española de Integridad Estructural - Grupo Español de Fractura SEIE-GEF, 2023)
Debido a sus condiciones de trabajo, la fatiga es uno de los modos de fallo más comunes en los engranajes. A pesar de que habitualmente se emplean diversos tratamientos para mejorar las propiedades mecánicas de los mismos, ...
Communications and Data Science for the Success of Vehicle-to-Grid Technologies: Current State and Future Trends
(MDPI, 2024)
Vehicle-to-grid (V2G) technology has emerged as a promising solution for enhancing the integration of electric vehicles (EVs) into the electric grid, offering benefits, such as distributed energy resource (DER) integration, ...
Depth-resolved mechanical behaviour of shot peened 7050-T7451 aluminium surfaces using in-situ synchrotron X-ray diffraction
(Elsevier, 2024)
We have assessed the elasto-plastic (sub)surface behaviour of 7050-T7451 aluminium alloy treated by shot peening using S110 steel shots of 300 μm in diameter and two different intensities, namely Almen intensity (A) of 3.4 ...
Automation across interconnected smart homes
