“…It shows that by increasing the magnetic flux density, the fluid viscosity increases (becomes semi-solid) as the magnetic particles orient in the The use of MR fluids to examine sandwich structures is a recent scientific advancement. The vibration, dynamic, and stability characteristics of sandwich structures such as circular plates, shells, structures, panels, and cylindrical panels are investigated [13,14]. Many research works have concentrated on testing, numerical analysis, and mathematical modelling of field-dependent properties in the structure category [15][16][17].…”

The stiffness and damping of a flexible smart cantilever structure controlled by a magnetic field is investigated in this research. The cantilever structure is fabricated by using flexible polyvinyl chloride as a host structure of rectangular cross-section embedded with magnetorheological (MR) fluid. The deflection of the cantilever structure at the free end is used to analyze the stiffness change of the cantilever structure. The stiffness of the specimen with MR fluid at magnetic flux density of 0.171T is greater than that of the specimen without subjected to magnetic field. The strength of the applied magnetic field is directly related to the structure’s stiffness. Under the influence of a magnetic field, the MR fluid embedded inside the flexible PVC cantilever structure significantly dampens the vibrations of the structure.

“…Vibrations are defined as a physical phenomenon characterized by alternating movements of material points in relation to the equilibrium position, spreading in gaseous, liquid (Kolekar et al, 2019) and solid media (Kang, 2017). The concept of vibration, often in literature, is synonymous with the concept of vibrations, is defined as vibrations occurring in mechanical systems (Rimasauskiene et al, 2019), (Zhang & Xu, 2019) having a harmful effect on the environment, human or construction (Koradecka, 2008, Engel & Zawieska, 2010, Uzarczyk, 2006.…”

The publication presents the results of research on the statistically significant impact of the number of layers on vibration damping properties of vibroacoustic mats. The research was carried out on the author’s research stand. The research was carried out on sandwich systems made of polyurethane foam. The impact force of the analyzed variables was determined on the basis of constructed multiple regression models, the so-called multifactor models and determination of the standardized value β. The research was carried out using the PQStat software. In the models being built, the significance level was p < 0.05. Three statistically significant linear multivariate models for one-third frequencies were constructed: • 0-20000 Hz – a model for the entire frequency spectrum analysed during the tests, • 0-400 Hz – a model for frequencies generating construction vibrations that may affect the worker as general vibrations, • 50-20000 Hz – a model for frequencies that generate construction vibrations that can cause auditory sensations (noise). It was found: positive correlation of the number of layers in vibration damping systems with a third octave frequency of up to 400 Hz; negative correlation of the number of layers in vibration damping systems with a third octave frequency of 50 to 20000 Hz.

“…Its vibration behavior can be altered by the application of magnetic field due to controllability in the properties of MRF. Several research works have been performed on MRF sandwich beams due to their vibration suppression capabilities and have potential applications in flexible structures such as aircraft wing, automobile hood, appendage of space robot, and other structural applications [8]. When used in structural beam applications, the MRF functions in the pre-yield regime and shows a viscoelastic behavior with complex shear modulus relating to shear stress and shear strain [9].…”
