Electrorheological and magnetorheological fluids in blast resistant design applications

摘要: The performance of electrorheological (ER) and magnetorheological (MR) fluids under impulsively-applied loads is investigated. ER fluid device, which operating in the squeeze flow mode, tested with four different fluids, while MR device a commercially available shock absorber resistance controlled by small electromagnetic element. Both devices were an experimental rig, capable providing fast loading that represents typical explosive air or hydrocarbon type explosion. These seen to exhibit sufficient field-induced damping forces when subjected various mechanical electrical inputs hence, they are adaptable fixing characteristics for blast resistant structural members such as walls on offshore platforms. In addition, could be predicted theoretical model based assumption bi-viscous characteristic, was found compare very well acquired experimentally.
