Vibration Damping Characterization of Linseed oil based Elastomers for its Effectiveness to Attenuate Structural Vibration
Vibration damping properties of elastomers prepared from linseed oil were characterized by Dynamic mechanical analyzer (DMA) in a temperature range of -50 to 100 oC and frequency range of 5Hz to 1 kHz. The maximum damping loss factor, varies from 0.78 to 1.32, the room temperature (25 oC) loss factor, in the range of 0.56 to 1.08 and the temperature range ( ) for effective damping ( 0.3) varies from 63 oC to 74.4 oC in different elastomers. The elastomers behave as a good vibration damper both in lower and higher frequency range. Thus these elastomers exhibit good damping behaviour in a wide range of temperature and frequency, a primary requirement for practical damping applications. A modal constrained layer damping system (CLD) constructed utilizing these elastomers exhibits its potentiality to attenuate structural vibrations with respect to mild steel bare plate resonator under laboratory fabricated testing methodology.

[Show abstract] [Hide abstract] ABSTRACT: In light of recent demands of biobased materials, vegetable oils seem to have acquired special privileges among product designers as a feedstock chemical for preparation of potential polymeric materials. This chapter demonstrates different routes for preparation polymers from vegetable oil, highlighting the effects of rein¬ forcement and nano reinforcement on these polymers' physical properties.

[Show abstract] [Hide abstract] ABSTRACT: Subject to a voltage, dielectric elastomers (DEs) undergo large deformations, resulting in a wide array of applications in actuators and energy generators. In this paper, a novel potential application of DEs is presented that employs a DE as a vibration damper to achieve the vibration attenuation of a spring oscillator. Based on the developed model, the passive vibration control of the spring oscillator is investigated by utilizing the viscoelastic damping of the DE itself. Subsequently, the active vibration attenuation is studied by applying alternating oppositely-phased voltages at different frequencies, which applies to DEs with a relatively lower viscoelastic damping coefficient. In order to obtain a tunable and controllable vibration attenuation process, the corresponding desired voltage is calculated through the prescribed trend of stretch. The results indicate that the vibration attenuation can be tuned and specified by applying the calculated voltage.
- "Viscoelasticity, especially in the VHB-based DEs, induces large damping during actuation, which could play a significant role in vibration attenuation. In recent years, researchers have carried out extensive investigation about this damping behavior by taking advantage of the viscoelasticity of polymer materials484950515253. Also, as a macromolecular polymer, damping effects and the damping coefficient were introduced into the research of DEs by Xu et al . "
[Show abstract] [Hide abstract] ABSTRACT: The microbial synthesis of environment-friendly poly(3-hydroxybutyrate--co-3-hydroxyvalerate), PHBV, has been performed by using an alkaliphilic microorganism, Alkaliphilus oremlandii OhILAs strain (GenBank Accession number NR_043674.1), at pH 8 and at a temperature of 30–32 °C through the biodegradation of linseed oil-based elastomer. The yield of the copolymer on dry cell weight basis is 90 %. The elastomers used for the biodegradation have been synthesized by cationic polymerization technique. The yield of the PHBV copolymer also varies with the variation of linseed oil content (30–60 %) in the elastomer. Spectroscopic characterization (1H NMR and FTIR) of the accumulated product through biodegradation of linseed oil-based elastomers indicates that the accumulated product is a PHBV copolymer consisting of 13.85 mol% of 3-hydroxyvalerate unit. The differential scanning calorimetry (DSC) results indicate a decrease in the melting (T m) and glass transition temperature (T g) of PHBV copolymer with an increase in the content of linseed oil in the elastomer, which is used for the biodegradation. The gel permeation chromatography (GPC) results indicate that the weight average molecular weight (M w) of PHBV copolymer decreases with an increasing concentration of linseed oil in the elastomer. The surface morphology of the elastomer before and after biodegradation is observed under scanning electron microscope (SEM) and atomic force microscope (AFM); these results indicate about porous morphology of the biodegraded elastomer.
- "The major objective of this research work is the formation of biopolymer in microbial cell through biodegradation of linseed oil-based elastomers. The linseed oilbased elastomers are the substitute of non-biodegradable vibration damping polymeric materials like neoprene rubber, silicon rubber etc., and it has effectiveness to attenuate structural vibration in machinery, dynamic system and structural engineering ; after completing service tenures in different practical application, this material can be degraded to make it free from environmental hazards. Therefore, a recycling experimentation has been fabricated to produce functional polymer, i. e. PHA copolymers by employing this elastomer. "
