In the present work attention is focused on friction-yielding damper CAR1 (first prototype of Control-Absorb-Retain damper), which belongs to passive energy dissipation systems. This consists very simple materials; it does not need be accomplished in heavy industry so enables its use both developing and undeveloped countries. paper presents compares two alternative solutions with seismic retrof...

Original scientific paper Intelligent bionic leg (IBL) controlled by magneto-rheological (MR) damper is an advanced prosthesis. The structure of human knee joint and torque control methods of IBL knee joint are analysed. The bionic design of IBL with MR damper is introduced. The transfer function of IBL is gained by system identification and parameter tuning of PID control based on genetic algo...

This paper is devoted to the problem of finding optimized parameter combinations of automotive damper modules. Different cost functions using the amplitude spectrum of the excitation and the frequency response function of the car model will be investigated and it is shown that for three different arbitrary road excitations there exists a parameter combination of top mount stiffness, piston rod ...

The present study focusses on the damping force control of shear mode magnetorheological (MR) damper for seismic mitigations. Therefore, the semi-active MR damper which can control the vibration is analyzed both experimentally and numerically. Carbonyl iron is used as the magnetic particle and Castrol Magnetec oil as carrier fluid throughout the study. MR damper is designed and fabricated, and ...
