The Active Magnetorheological Support as an Element of Damping of Vibrations Transferred from the Ground to Large-Scale Structure Supports

Abstract

The active support of a large-scale structure, made up of two elements was designed and manufactured. The first of them - piezoelectric actuator, enables the simulations of vibrations transferred from the ground to the structure. In order to minimize vibrations transmitted through the ground to the construction, the second element of the active support - a system based on magnetorheological dampers was used. The active support enables the simulations of vibrations from the ground using a piezoelectric stack controlled in a reverse feedback loop. Control signals of the feedback loop are: the volume of deformation and vibrations in the selected structures node.

Modelling of Innovative Controllable Structures Made of Granular Materials

“…In authors opinion, special granular structures can compete with other popular "smart" materials such as MR fluids. A typical example of a practical engineering application of the investigated structures would be a granular controllable damper used for minimizing risks associated with earthquakes [25] or a part of a bumper minimizing harmful effects resulting in a collision between a vehicle and pedestrian [26].…”

Identification of sources, propagation and structure vibrations affecting men in means of transport based on the example of automotive vehicles

“…The influence of engine rotational speed and gear ratio on evaluation of human exposure to whole body vibration have been presented as the distribution of these exposure estimators and it is presented in Figs. 16.1-16.2.…”

Investigation of an off-road vehicle equipped with magnetorheological dampers

“…[3][4][5] Recently, many other investigations (cf. previous studies [6][7][8][9][10] for example) provided additional know-how on developing effective vehicle, train, or aircraft active or semi-active suspension systems with the use of different smart materials. It should be noted that many modern active and semi-active vibration or isolation systems utilize also standard materials, that is, hydraulic dampers controlled by electromagnetic or piezoelectric valves.…”
