“…В разработанной модели (3) в явном виде отсутствует продолжительность дейс твия силы трения. Исходя из того, что при испытаниях скорость вращения абразива может варьироваться в широких пределах, в модели используется не продолжительность истирания, а количество оборотов абразива, которое при заданной скорости вращения позволяет рассчитать продолжительность истирания (τ, мин) по формуле τ = N/w, (5) где w  скорость вращения абразива, обороты/мин. Модель (3) может использоваться не только для прогнозирования уменьшения массы образцов, но и толщины, что можно сделать по установленной экспериментально величине ∆m, площади истирания (S, м 2 ) и плотности образцов (р, кг/м 3 ).…”

“…Significant improvement in structural damping and dynamic viscoelastic loss is reported in OMMT-filled nitrile rubber/polyvinyl chloride (NBR-PVC) 70/30 (w/w) nanocomposites. Aluminum beam vibration damping in a constrained layer damping (CLD) revealed that NVC73-5OMMT produced reliably high damping at all modal frequencies and emphasized that it might be caused by improved exfoliation and uniform clay dispersion in the matrix [20]. The loss factor of hybrid structures and laminates containing viscoelastic materials with experimental and numerical calculations was reported [21][22][23][24].…”

An experimental and numerical study on the mechanical and damping properties of styrene-butadiene rubber (SBR) composites with graphene nanoparticles (GNP) and carbon black (CB) is presented in this paper. The composites were tested for mechanical properties such as hardness and tensile strength. It is observed that the composites with GNP & CB fillers have higher stiffness and percentage elongation for failure. A scale model of the chassis was subjected to forced vibration to find the damping properties of each of the prepared composites. The experimental results were used to create a numerical model in ANSYS software using Yeoh's hyper-elastic model to generate a hyper-elastic material to simulate the composite property and to perform harmonic response analysis in ANSYS. The results from experiments and theoretical findings exhibited good agreement.

We report efficacious vibration damping of carbon black reinforced nitrile butadiene rubber‐polyvinyl chloride blend (NVC) vulcanizates in a constrained layer damping (CLD) configuration. The objective is to compare numerical simulations using finite element method (FEM) and the widely used Ross‐Kerwin‐Ungar (RKU) model with the experimental results. NVC blend (50:50 by weight), was compounded with carbon black as reinforcing filler and vulcanized using a sulfur‐based curative system. Significant reinforcement and toughening were observed for the carbon black reinforced vulcanizates compared to the pristine blend. The viscoelastic properties of the vulcanizates were assessed using dynamic mechanical analysis (DMA), exploring their behavior concerning temperature variations and different frequencies to generate the Prony series coefficients for input in FEM analysis. Vibration damping experiments were conducted using the Oberst beam method in a single cantilever mode, with steel as the vibrating substrate, aluminum as the constraining layer, and the NVC vulcanizates as viscoelastic materials (VEM). Numerical simulations were performed using FEM to analyze mode shapes and frequency response function (FRF), and the RKU model was employed to quantify CLD system loss factors (SLF). The salient finding of this study was the observed SLF values in the range of 0.08–0.20 in the frequency regime of 200–2000 Hz. These values qualify the studied material as effective VEMs for CLD treatment of structural vibrations. This study supports design optimization efforts in a wide range of engineering applications where effective vibration damping is critical.Highlights Enhancement of NVC blend properties through carbon black reinforcement. Detailed analysis of viscoelastic behavior using DMA. Validation of findings through experimental modal analysis. Promising results in terms of system loss factors for CLD applications.
