This feature has been realized using two coaxially aligned eccentric rotors, which are driven by DC motors independently. The prototype of the device has been built, where mechanical components are integrated on a frame with two optical sensors for the measurement of angular velocity and phase angle. The system is equipped with a digital controller. Simulations confirm the results of analytical investigations and they allow us to model the sampling method of the signals of the angular velocity and the phase angle between the rotors. Furthermore, we model the discrete behavior of the controller, which is a PI controller for the angular velocities and a PID controller for the phase angle. Finally, simulation results are compared to experimental ones, which show that the Dual Excenter concept is feasible.}, year = {2015}, eissn = {1095-8568}, pages = {98-107}, orcid-numbers = {Miklós, Ákos/0000-0002-8393-0443; Szabó, Zsolt/0000-0002-3650-1662} } @CONFERENCE{MTMT:31910495, title = {Experimental and analytical investigation of a fluttering bridge section model}, url = {https://m2.mtmt.hu/api/publication/31910495}, author = {Szabó, Zsolt and Stépán, Gábor and Zelei, Ambrus}, booktitle = {Proceedings of ICSV 21 – International Congress on Sound and Vibration}, unique-id = {31910495}, year = {2014}, pages = {2663-2670}, orcid-numbers = {Szabó, Zsolt/0000-0002-3650-1662; Stépán, Gábor/0000-0003-0309-2409; Zelei, Ambrus/0000-0002-9983-5483} } @inproceedings{MTMT:3107186, title = {Experimental and analytical investigation of a fluttering bridge section model}, url = {https://m2.mtmt.hu/api/publication/3107186}, author = {Szabó, Zsolt and Stépán, Gábor and Zelei, Ambrus}, booktitle = {21st International Congress on Sound and Vibration 2014, ICSV 2014}, unique-id = {3107186}, year = {2014}, pages = {2663-2670}, orcid-numbers = {Szabó, Zsolt/0000-0002-3650-1662; Stépán, Gábor/0000-0003-0309-2409; Zelei, Ambrus/0000-0002-9983-5483} } @CONFERENCE{MTMT:2786036, title = {Advanced tactile feedback with dual-rotor vibrotactor}, url = {https://m2.mtmt.hu/api/publication/2786036}, author = {Miklós, Ákos and Szabó, Zsolt}, booktitle = {Investigating Dynamics in Engineering and Applied Science (IDEAS)}, unique-id = {2786036}, abstract = {A novel solution is presented for generating advanced tactile feedback in haptic applications.

Today’s common vibroactuators, like the ones in cell phones or in hand-held tools, mostly contain only one eccentric rotor, which is driven by an electric motor. One disadvantage of such devices is that the frequency and amplitude of the vibration is not independent, so they can only be used at a limited frequency range. Therefore a novel vibroactuator design was developed, which is called “dual excenter”. This device contains two coaxially positioned eccentric rotors, which are driven by DC motors, and so the common eccentricity of the dual-rotor system can be adjusted during operation. In this talk a multi-body model for the dual-rotor system is proposed, and the mechanical behaviour of the ”dual excenter” is investigated with classical tools of mechanics. The equations of motion are derived by the Lagrangian equation, where the electric motors are considered with their steady-state performance. By means of the governing equations, the stationary motions of the system and their linear stability are analysed. Two phenomena, the mechanical synchronization and the power resonance can be captured, which have major influence on the behaviour of the device. Simulations show that with a simple PD controller it is possible to reach fast and robust system behaviour. Some design issues will also be discussed, which can influence the stability of the synchronized stationary motions.}, year = {2013}, orcid-numbers = {Miklós, Ákos/0000-0002-8393-0443; Szabó, Zsolt/0000-0002-3650-1662} } @CONFERENCE{MTMT:2692724, title = {Mechanical Synchronisation in Dual-Rotor Vibroactuator}, url = {https://m2.mtmt.hu/api/publication/2692724}, author = {Miklós, Ákos and Szabó, Zsolt}, booktitle = {Proceedings in Applied Mathematics and Mechanics}, doi = {10.1002/pamm.201310016}, unique-id = {2692724}, abstract = {In the present work the mechanical behaviour of a dual-rotor vibrotactor has been investigated with special attention to its stationary motions and their linear stability.
