Motion and vibration control of a slewing flexible structure by SMA actuators and parameter sensitivity analysis
(2015-11-01)
This work presents two approaches to the problem of vibration and positioning control of a flexible structural beam driven by a DC motor. The position is controlled by the current applied to the DC motor armature. A Shape ...
Respostas neuromusculares agudas a estimulação vibratória local no exercício de flexão de cotovelo em banco scott
(Universidade Federal de Minas GeraisUFMG, 2013-04-26)
The deleterious effects on health-related vibration in the field of physical medicine and occupational therapy have been previously reported. In sports these rules arent existents, although in several sports athletes undergo ...
Aplicação do shunt piezoelétrico para controle passivo de chatter no processo de torneamento da liga Ti-6Al-4V ELI
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Mecânica - PPGEMecCâmpus São Carlos, 2022-08-01)
One of the main limitations for increasing the productivity of machining processes is the emergence of self-excited vibrations. This type of phenomenon, commonly called chatter, arises due to the interaction of the cutting ...
