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.

The concept utilizes the benefits of the eccentric rotating mass (ERM) vibrotactors and eliminates the problem of the frequency-dependent amplitude by using two eccentric rotors. Operational region of the dual-rotor vibrotactor is showed in the frequency-amplitude domain considering tactile sensing threshold of the human skin, and the possibility of changing the intensity of the tactile stimuli by the dual-rotor vibrotactor is compared to common ERM vibrotactors.

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.

After the introduction of the used mechanical model, the formulae for the stationary motions are given, and characteristic stablity charts are presented. The linear stability is investigated for uncontrolled and controlled system as well. LA - English DB - MTMT ER -
