Influence of carbon black and plasticisers on dynamic properties of isotropic magnetosensitive natural rubber

Abstract

The dynamic shear modulus of magnetosensitive (MS) natural rubber composites is experimentally studied, where influences of carbon black, plasticiser and iron particle concentrations are investigated at various dynamic shear strain amplitudes and external magnetic fields within the lower structure borne frequency range. The iron particles embedded in natural rubber are irregularly shaped and randomly distributed; the plasticisers simplify the iron particle blending process, while carbon black reduces the production costs and improves the mechanical properties. The results show that the relative MS effect on the shear modulus magnitude increases with increased plasticiser and iron particle concentration and decreases with increased carbon black concentration. Furthermore, their relative contributions are quantified. Consequently, the study provides a basis for optimising the composition of MS natural rubber to meet a variety of requirements, including those of vibration isolation, a promising application area for MS materials.

Multistep analysis of the mechanical performance of an air spring

New methods for testing air springs have received a lot of interest in recent years. In this article APDL (ANSYS parametric design language) was utilized to simulate static and dynamic test process of air springs. In the simulation, multiple load steps solution was carried out through APDL *DO‐LOOP and array parameter method. The program (capsule volume calculating macro) based on scatter sum method enabled the loop. The scalar quantity PRESSURE was established as inner tracking parameter to update inner pressure. Table parameter PRESSURES was established as inner pressure output parameter to export inner pressure of each load step. According to rubber elastic behavior and cord‐rubber composite aeolotropy, hyper elastic element and layer element were preferred for simulation. Comparison was done between static simulation results and corresponding test data to prove feasibility of multistep analysis. In consequence, some major parameters such as cord angle, initial inner pressure, and auxiliary chamber volume were taken into account, which have remarkable effect on static mechanical performance of EQ6111 air spring. Finally, the same method was applied to the simulation of dynamic test process, achieving abundant analysis results according to every 0.5 Hz increment of load frequencies varying from 0.5 to 2.5 Hz. Load frequency threw remarkable effect on the dynamic mechanical performance of EQ6111 air spring, because inertial effect and damping effect played important roles therein. The study aims to make contribution to the development of platform of air spring simulation and parameterized design (PASSPD). © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009

Mechanical and vibration isolation behaviour of acrylonitrile-butadiene rubber/multi-walled carbon nanotube composite machine mounts

An effective analytical-experimental test method is used in the current work to characterize the vibration isolation performance of nitrile-butadiene rubber (NBR) reinforced with multi-walled carbon nanotubes (MWCNTs). A series of specimens were manufactured with 10 different NBR/MWCNTs concentrations (0 to 20wt% MWCNTs). In order to determine the static compression stiffness and hysteresis of the mounts, compression and cyclic tests were conducted. The vibration isolation properties were determined through the analysis of the transmissibility of a suitably designed test system. NBR’s mechanical properties and vibration isolation properties were improved with the addition MWCNTs, suggesting that the enhancement of NBR with MWCNTs was rather effective. Considering the obtained results, the dynamic stiffness of NBR and its capacity to isolate vibration can be adjusted by controlling the proportion of MWCNTs.     

Dynamic properties of rubber vibration isolators and antivibration performance of ethylene–propylene–diene monomer/nylon 6 blend systems

This article examines thermoplastic elastomers (TPEs) and thermoplastic vulcanizates (TPVs) as two types of elastomers from melt-blended and dynamically vulcanized ethylene–propylene–diene monomer (EPDM) rubber materials and nylon 6 plastic materials. A series of investigations were conducted on the mechanical properties, morphology, dynamic mechanical properties, hysteresis behavior, and dynamic antivibration properties with different nylon 6 contents. The experimental results showed that the incompatibility between EPDM and nylon 6 led to the easy destruction of the TPV materials in two interfacial polymers upon the application of an external force. Thus, after a dynamic vulcanization process, the mechanical properties of the EPDM/nylon 6 blends were not as good as those of the TPE materials. In terms of morphology, nylon 6 plastics were uniformly distributed in the EPDM/nylon 6 blends during the EPDM rubber phase before vulcanization was performed. After the dynamic vulcanization, phase inversion was produced in which rubber microparticles were formed and dispersed in the nylon 6 plastic phase. The results of dynamic mechanical analysis, compression vibration hysteresis behavior, and dynamic property antivibration experiments showed that the blends provided better vibration isolation and antivibration performance after the amount of nylon 6 was increased and EPDM and nylon 6 were blended through dynamic vulcanization. © 2008 Wiley Periodicals, Inc.
