Numerical Fretting© Wear Simulation of Deep Groove Ball Bearing Under Radial Variable Load
(Springer, 2022)
Bearing has become one of the most widely used mechanical components over the world. Even this component has been extensively studied, there exist especial applications or untypical operating conditions that still must be ...
An Innovative Energy Harvesting Shock Absorber System for Motorbikes
(IEEE, 2022)
This article presents an innovative energy recovery shock absorber system for motorcycles. The shock absorber is named synchronous pulley - energy harvesting shock absorber (SP-EHSA). The SP-EHSA is the first system ...
Surface topography irregularities generated by broaching
(Elsevier Ltd., 2022)
Surface topography irregularities generated by broaching are analysed. Experimental tests were carried out on three workpiece materials: AISI 1045, Ti-6Al-4V, and Inconel 718, varying the cutting speed, rise per tooth, and ...
Analysis of the Tool Stick-Out Influence on Machining Chatter
(2021)
Increased stability in machining processes is highly desired by all machining industries when vibrations and specially chatter occur. This phenomenon is defined as a self-excited vibration that occurs due to the regeneration ...
First-year university students entrepreneurial competence: Exploring the relationship between grit, creative self-efficacy and entrepreneurial self-efficacy
(Universitat Politècnica de València, 2021)
Grit, creative self-efficacy and entrepreneurial self-efficacy have been
associated with the development of entrepreneurial behaviours that can
prepare students for a rapidly changing world of work. The main purpose ...
Contact pressure and sliding velocity ranges in sheet metal forming simulations
(2021)
In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ...
Influences of Cutting Speed and Material Constitutive Models on Chip Formation and their Effects on the Results of Ti6Al4V Orthogonal Cutting Simulation
(2021)
The highly used Ti6Al4V alloy is a well know hard-to-machine material. The modelling of orthogonal cutting process of Ti6Al4V attract the interest of many researchers as it often generates serrated chips. The purpose of ...
A Controlled Thermoalgesic Stimulation Device for Exploring Novel Pain Perception Biomarkers
(IEEE, 2021)
Objective: To develop a new device for identifying physiological markers of pain perception by reading the brain's electrical activity and hemodynamic interactions while applying thermoalgesic stimulation. Methods: We ...
Reactive power limits of Cascaded H-Bridge STATCOMs in star and delta configuration under negative-sequence current withstanding
(Elsevier Ltd., 2022)
Flexible AC Transmission System devices (FATCS) and in particular Static Synchronous Compensators (STATCOM) play a key role in the evolution of the modern power grids to the future smart grids. The STATCOM is used in an ...
Petri net-based semi-compiled code generation for programmable logic controllers
(MDPI, 2021)
Industrial discrete event dynamic systems (DEDSs) are commonly modeled by means of Petri nets (PNs). PNs have the capability to model behaviors such as concurrency, synchronization, and resource sharing, compared to a step ...
