Abstract
In this paper, we propose a new movement mechanism using a resonance phenomenon. We use the phase-matched twist mode of the plate to the moving mechanism. By the synthesis of rigid body mode and twist mode, the rear endpoint of the plate vibrates in an elliptical trajectory. Driving force is generated by this trajectory. To realize this movement mechanism, we fabricated the small test model. We determined the shape suitable to the twist mode by FEM eigenvalue analysis. From the result of driving experiment, velocity of the model has been increased rapidly by the twist mode. From these results, we were able to find the possibility of movement mechanism based on twist mode of plate.
