Effect of surface integrity generated by machining on isothermal low cycle fatigue performance of Inconel 718
(Elsevier Ltd., 2022)
Critical aero-engine components such as turbine discs must withstand severe cyclic stresses, which can eventually lead to low cycle fatigue (LCF) failures. These components are made of difficult-to-cut alloys and machining ...
Cost-optimal Integration of Innovative Powertrain Technologies into Rail Vehicles
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2022)
Railway is an essential transportation mode in nowadays society, both for passengers and goods. Considering that the relation between the carried passenger activity and the derived pollutant emissions is lower than in road ...
A data-driven long-term metocean data forecasting approach for the design of marine renewable energy systems
(Elsevier, 2022)
The potential of Marine Renewable Energy (MRE) systems is usually evaluated based on recent metocean data and assuming the stationarity of the MRE resource. Yet, different studies in the literature have shown long-term ...
Fast and Accurate Vibration Response Calculation Procedure for Permanent Magnet Synchronous Machines
(IEEE, 2022)
The vibration of the stator frame due to electromagnetic forces is one of the main noise and vibration sources of electric machines. In some applications, due to the wide variety of working conditions, design optimizations ...
Numerical analysis of AISI 321 alloy material parameters on rubber pad diaphragm forming
(IOP Publishing, 2022)
Rubber pad diaphragm forming is a technology that uses a rigid die in conjunction with a flexible polyurethane tool and fluid pressure action in order to shape metal sheets. In this process, the action of the fluid forms ...
Efecto de la separación fibra-matriz sobre las propiedades mecánicas de una viga forjada en poliamida reforzada con fibra de vidrioEffect of the fiber-matrix separation on the mechanical properties of a fiberglass reinforced polyamide forged beam
(Scipedia, 2022)
In the present work, ribbed beams have been manufactured by forging fiberglassreinforced polyamide using two different temperatures. The higher processing temperature studied (300 ºC) ensures the filling of the mold in the ...
Cybersecurity Evaluation Methodology based on Metrics for Industrial Embedded Systems
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2022)
During the last decades, Embedded Systems (ESs) have evolved from isolated systems into a fully connected devices. Today, due to the development of processing capabilities, ESs have the ability to control or manage a wide ...
Time-Frequency Analysis of Experimental Measurements for the Determination of EMI Noise Generators in Power Converters
(MDPI, 2022)
In the context of recent decades in which there has been great development in power electronics systems with increasingly better operating characteristics, the study of the factors that affect the behaviour of these systems ...
Hole quality analysis of AISI 304-GFRP stacks using robotic drilling
(Elsevier B.V., 2022)
Although drilling of FRP - metal stacks is the most widely used machining operation for these materials, it remains challenging in many aspects (tool wear, vibrations, delamination, poor surface finish, etc). In this ...
Numerical modelling of the drag finishing process at a macroscopic scale to optimize surface roughness improvement on additively manufactured (SLM) Inconel 718 parts
(Elsevier B.V., 2022)
Drag finishing is one of the mass finishing processes that enhances surface roughness on complex and rough parts produced by additive manufacturing. This paper proposes a model to simulate abrasive media flowing around the ...
Simulation-based Metamorphic Testing of Cyber-Physical Systems
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2022)
Cyber-Physical Systems (CPSs) are heterogeneous systems in which software components and physical processes interact with each other. These systems have strict requirements that are difficult to verify, resulting in very ...
Modular Battery Systems’ Accessible Energy Analysis
(2022)
One of the main concerns regarding traditional battery energy storage systems (BESS) is how to solve issues related to cell inhomogeneities. This problem commonly ends up reducing the accessible energy level, especially ...
Surface integrity evaluation within dry grinding process on automotive gears
(Elsevier B.V., 2022)
Gears are essential components in automotive transmissions and their performance directly depends on the flanks surface integrity. To date the gears whole production chain do not use lubricants, except the final step of ...
Fibre-Wood Laminate Biocomposites: Seawater Immersion Effects on Flexural and Low Energy Impact Properties
(MDPI, 2022)
The present paper explores a new concept of a hybrid eco-composite by substituting the natural fibre plies with thin wood veneers. The new composite, named Fibre–Wood Laminate (FWL), is inspired by fibre–metal laminate ...
