In this paper, performance of passive vibration isolators, namely rotational / linear tuned mass dampers (TMD) and lever type vibration isolators (LVI), are investigated under different configurations for optimal ride comfort. TMDs reduce vibration levels by absorbing the energy of the system, especially around natural frequencies with the help of viscous dampers. Two types of TMDs, rotational and linear, are investigated in this study. Although linear TMDs can be more easily implemented on suspension systems, rotational TMDs show better performance in reducing vibration levels. The reason is that, the inertia effect of rotational TMDs is higher than linear TMDs. In order to obtain better results with TMDs, a study on different possible configurations is conducted. A plate, with very small mass, is added between sprung and unsprung masses without changing the original suspension spring stiffness and damping coefficients and acts as a support for in-series TMD applications. Finally, LVIs are implemented to reduce sprung mass acceleration and more satisfactory results are obtained especially around body bounce frequency.

Ride comfort improvement by application of tuned mass dampers and lever type vibration isolators Aydan, Göksu; Ciğeroğlu, Ender; Department of Mechanical Engineering (2010) In this study, the efficiency of linear and rotational tuned mass dampers (TMD) and lever type vibration isolators (LVI) in improving ride comfort is investigated based on a vehicle quarter-car model. TMDs reduce vibration levels by absorbing the energy of the system, especially at their natural frequencies. Both types of TMDs are investigated in the first part of this study. Although linear TMDs can be implemented more easily on suspension systems, rotational TMDs show better performance in reducing vibrat...
Implementation and comparison of reconstruction algorithms for magnetic resonance-electric impedance tomography (mr-eit) Martin Lorca, Dario; Eyüboğlu, Behçet Murat; Department of Biomedical Engineering (2007) In magnetic resonance electrical impedance tomography (MR-EIT), crosssectional images of a conductivity distribution are reconstructed. When current is injected to a conductor, it generates a magnetic field, which can be measured by a magnetic resonance imaging (MRI) scanner. MR-EIT reconstruction algorithms can be grouped into two: current density based reconstruction algorithms (Type-I) and magnetic flux density based reconstruction algorithms (Type-II). The aim of this study is to implement a series of r...
A(p)/V-p specific inelastic displacement ratio for the seismic response estimation of SDOF structures subjected to sequential near fault pulse type ground motion records DURUCAN, CENGİZHAN; Durucan, Ayse Rusen (2016-10-01) This research study is focused on an improved statistical equation proposed to estimate the inelastic displacement ratio, C-1, of structures subjected to sequential (pre-shock, main shock, after shock) pulse type near fault (NF) ground motions. Proposed equation considers the effects of fundamental vibration period of the structure, T, lateral strength ratio, R, and frequency content of the design earthquake on the variation of the response. Frequency content of the design earthquake, represented by the A(p...
Utilization of motor current based torque feedback to improve the transparency of haptic interfaces Baser, Ozgur; Konukseven, Erhan İlhan (2012-06-01) In this paper motor current based torque feedback compensator is utilized in actuator space together with a closed loop impedance control algorithm instead of model based compensator to improve the transparency performance of haptic interfaces; moreover, a novel transparency evaluation metric is developed to evaluate the transparency performance of these devices. The proposed control algorithm is experimentally tested on a 1 DOF haptic device by employing a low-cost current sensor. It is also tested on a MA...
Implementation of sensorless vector control drive with current position estimation Filci, Tayfun; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2016) In this thesis, an algorithm will be developed and implemented online for the estimation of rotor position from the rotor slot harmonics in stator currents. Experiments will be done on an inverter driven induction motor hardware, and the performance of the position detection algorithm will be evaluated in comparison with commercial encoder outputs.
