Analysis of the dependence between a temperature and working parameters of the MR damper
(Wydawnictwa AGH, 2007) Bajkowski, Jerzy; Bajkowski, Marcin; Grzesikiewicz, Wiesław; Sofonea, Mircea; Shillor, Meir; Zalewski, Robert
In this paper detailed description of temperature influence on MR damper working parameters has been described. Prototype of such a device and its mathematical description taking into considerations a thermal balance, have been proposed. Basing on experimental results, a connection between temperature and operating parameters of tested MR damper has been revealed.

Facility for investigating the vibration of the plate with magnetorheological fluid
(2012) Snamina, Jacek
This study briefly outlines the structure of the test facility for investigating the behaviour of a sandwich plate filled with magnetorheological (MR) fluid. The plate has two outer layers made of aluminium and the space between them is filled with MR fluid. The test facility is engineered within the framework of the research project focused on vibration reduction in beams and plates using MR fluids. The paper outlines the design of the test facility and the measurement equipment. Measurement data are summarised, including the free and forced vibration of the plate.

Vibration parameters of sandwich beams with two types of MR fluid
(2011) Romaszko, Mateusz; Pakuła, Sebastian; Sapiński, Bogdan; Snamina, Jacek
The study presents the results of laboratory studies on free vibrations of sandwich beams filled with magnetorheological (MR) fluids characterised by various proportions of ferromagnetic particles by weight. Based on the obtained results, it was possible to determine the impact of the content of the particles in question on the natural frequency of free vibrations and the dimensionless damping coefficient of beam.
