The purpose of this study was to solve the problem that damping rubber or silicone oil torsional dampers used in crankshafts is not adjustable and cannot effectively control vibration at different resonant frequencies. Based on controlled rheological properties magnetorheological (MR) smart materials, designed a new type variable MR damper (MRTD) proposed semi-active method crankshaft under mul...

This paper proposes a local approach for the on-line tuning of semi-active vibration control unit, which is set to reduce resonant response target low-order flexural modes distributed structures subject broadband stochastic disturbances. The idea have multiple self-contained units, can be fixed on thin walled and sound radiation at low audio frequencies where dynamics controlled by modes. unit ...

Semi-active control systems have been widely studied over the last 20 years. The range of applications includes automotive suspensions, seismic vibration mitigation, large bridges vibration control, knee prosthesis, among others. Semi-active actuators have a complex dynamics, and interaction between actuator and plant cannot be ignored in control design. This is specially true for magneto-rheol...

To control structures against wind and earthquake excitations, Adaptive Neuro Fuzzy Inference Systems and Neural Networks are combined in this study. The control scheme consists of an ANFIS inverse model of the structure to assess the control force. Considering existing ANFIS controllers, which require a second controller to generate training data, the authors’ approach does not need anot...
