Combination of acoustic emission and vibratory measure-ments to characterize an ultrasonic vibration assisted ball burnishing tool for a lathe
(2021-07-14)
Article
Accés obertIn this paper, a resonant system that produces a movement of low amplitude and ultrasonic frequency is used to achieve the vibration assistance in a ball-burnishing process. A full vibration characterization of this process ... -
High-precision time-of-flight determination algorithm for ultrasonic flow measurement
(2019)
Article
Accés obertCommercial time-of-flight (TOF) ultrasonic flowme- ters are rapidly expanding in the general industry. Among the different techniques that can be applied to determine the TOF of ultrasonic waves, the cross-correlation ... -

Preparation of medicated polylactide micropieces by means of ultrasonic technology
(Multidisciplinary Digital Publishing Institute, 2019-06-01)
Article
Accés obertA technology based on the application of ultrasound as an energy source was applied to get polylactide (PLA) micropieces with minimum degradation and processing time. This requirement could be even shorter than 1.5 s. The ... -
Sistema de localització per ultrasons
(Universitat Politècnica de Catalunya, 2016-10)
Projecte/Treball Final de Carrera
Accés restringit per decisió de l'autorThe project aims to develop an integral hardware-software system to detect the position of an object in the near zone using a low cost ultra-wave transducer. The project will use a development board from the same author. -
Ultrasonic vibration-assisted ball burnishing tool for a lathe characterized by acoustic emission and vibratory measurements
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-01)
Article
Accés obertThis paper focuses on a resonant system used to induce a low-amplitude movement and ultrasonic frequency to complement a ball burnishing process on a lathe. The system was characterized through the combination of different ...
