The statistical mechanics of directed line-like objects, such as directed polymers in an external field, strands of dipoles in both ferroand electrorheological fluids, and flux lines in high-TC superconductors bears a close resemblance to the quantum mechanics of bosons in 2 + 1 dimensions. We show that single component and binary mixture critical phenomena in these systems are in the universal...

Electrorheological fluids constitute a type of colloids that can vary their rheological characteristics upon the application of an electric field. The recently discovered giant electrorheological (GER) effect breaks the upper bound of the traditional ER effect, but a microscopic explanation is still lacking. By using molecular dynamics to simulate the urea-silicone oil mixture trapped in a nano...

This paper presents real-time control characteristics of an electrorheological (ER) suspension system via a fuzzy sliding mode control algorithm which is formulated in a discrete-time manner by considering the sampling rate of an electronic control unit for a vehicle system. A quarter-vehicle system consisting of sprung mass, spring, tire and a cylindrical ER damper (shock absorber) is construc...

Viscoelastic and fluid film dampers are the main two categories of damping devices used for the vibration suppression in machines and mechanical structures. Although cost effective and of small size and weight, they are affected by several drawbacks: the need of elaborate tuning to compensate the effects of temperature and frequency, the ageing of the material and their passive nature that does...

Simultaneous measurements of viscoelasticity and electrical conductivity are performed to study the dynamic characteristics of structures formed in a highly concentrated electrorheological suspension under a dc electric field of 1.8 kV/mm. Small amplitude oscillatory shear measurements reveal that there is no direct correlationbetween theelasticmodulusand theelectrical conductivity of the suspe...
