This article proposes a simple physical-based model to describe and predict the performance of axially compressed magnetorheological elastomer cylinders used as vibration shock absorbers. The describes macroscopic stiffness changes because an externally applied magnetic field from microscopic composite cell silicone rubber carbonyl iron particle. Despite neglecting material hyperelasticity, ani...

This paper presents a constrained robust H? controller design of active suspension system for in-wheel-independent-drive electric vehicles considering control constraint and parameter variation. In the model, uncertainties sprung mass are analyzed via linear fraction transformation, perturbation bounds can be also limited, then uncertain quarter-vehicle model where in-wheel motor is suspended a...

Placing porous media in a water tank can change the dynamic characteristics of sloshing fluid. Its extra damping effect mitigate and, thereby, protect integrity liquefied natural gas tank. In addition, out-of-phase force enables to serve as vibration absorber for floating structures ocean environment. The influence on wave-induced fluid and associated interaction with substructure ambient wave ...

ABSTRACT The objective of the paper is to explain a modern Hilbert transform method for analysis and identification of mechanical non-linear vibration structures in the case of quasiperiodic signals. This special kind of periodicity arises in experimental vibration signals. The method is based on the Hilbert transform of input and output signals in a time domain to extract the instantaneous dyn...
