The development of fail-safe magnetorheological damper
Hašlík, Igor ; Růžička, Bronislav (referee) ; Kubík, Michal (advisor)
This diploma thesis deals with an engineering design of a fail-safe magnetorheological (MR) damper capable of semi-active control. The first part of the thesis is devoted to the current state of knowledge of fail-safe MR dampers and permanent magnets contained in these dampers. The next part contains an engineering design of a fail-safe MR damper, made using FEM simulations, and its subsequent testing in terms of magnetic and hydraulic properties. Finally, a design of a fail-safe MR damper with fast response time was made and simulated using verified FEM analysis. Fast response time is ensured by limiting the generation of eddy currents in the piston core by grooving.

Design of fail-safe magnetorheological damper
Hašlík, Igor ; Novák, Petr (referee) ; Kubík, Michal (advisor)
This Bachelor’s thesis deals with an engineering design of so-called fail-safe system applied to a magnetorheological damper. In the beginning there is mentioned an essential knowledge needed for developing of such a device. The following part shows some of the current designs. Next part consists of few concept designs. One of those concepts was chosen to be processed in the engineering part. Finally a simplified magnetic and hydraulic model of the final design is calculated.
