On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...
SDRE applied to position and vibration control of a robot manipulator with a flexible link
(2016-01-01)
This paper presents position and vibration control of a flexible robot composed of two rigid and one flexible links. Position is controlled by the current applied to the DC motor armature. To control vibrations of the ...
On energy harvesting from ambient vibrations through an oscillating pendulum system fixed to a suspended plataform
(2020-01-01)
In this paper, we present numerical investigations of a pendulum system to harvest energy from the ambient. The mathematical model of the pendulum is obtained considering a harmonic displacement of its base. For power ...

Análise de vibrações em um torno da UTFPR Guarapuava
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia MecânicaUTFPR, 2020-11-12)
Vibration is a very common phenomenon and is present both in our daily lives and in industrial environments. However, vibration can often be undesirable, as it causes many problems in mechanical equipment, which can cause ...
An investigation into the simultaneous use of a resonator as an energy harvester and a vibration absorber
(Elsevier B.V., 2014-02-28)
A mass-spring-damper system is at the core of both a vibration absorber and a harvester of energy from ambient vibrations. If such a device is attached to a structure that has a high impedance, then it will have very little ...
