Effect of the loading-rate and stress state on the constitutive modelling and fracture of 2205 Duplex stainless steel
(Elsevier, 2024)
Shear cutting is a high-speed forming process where material separation is involved. The nature of the process leads to high strain rates and temperatures on the sheared zone of the material subjected to the operation. In ...
Uncertainty Distribution Assessment of Jiles-Atherton Parameter Estimation for Inrush Current Studies
(IEEE, 2024)
Transformers are one of the key assets in AC distribution grids and renewable power integration. During transformer energization inrush currents appear, which lead to transformer degradation and can cause grid instability ...
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 ...
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 ...
Modelizado bidimensional de engranajes cilíndricos por elementos finitos
(UNED, 2018)
El análisis de la distribución de carga, rigidez y error de transmisión de engranajes cilíndricos es fundamental para predecir los efectos de la geometría del dentado sobre las vibraciones, resistencia y eficiencia. El uso ...
Influence of thermal distortion on load distribution, transmission error and premature contact
(INSA, 2018)
The influence of thermally-induced geometry distortions on representative gear parameters such as load distribution or transmission error is analysed. An analytical load distribution model is coupled to a thermal ...
Influence of thermal distortion on spur gear tooth contact
(American Gear Manufacturers Association (AGMA), 2018)
The reduction of component size and oil volume of current automotive and aeronautical transmissions along with the increasing input speed are pushing gear teeth bulk temperatures to their scuffing limit. Although new ...
GaN Based Multiphasic Drive for Electric Vehicles
(VDE Verlag, 2023)
This paper presents the design of a six-phase two-level Voltage Source Inverter (VSI) using Gallium Nitride (GaN) semiconductors. The proposed topology consists of three full-bridge branches, where the GaN semiconductors ...
