Development of Manual Excitation Type 3-DOF Vibration Teaching Materials

Abstract

The authors have developed several teaching materials of motion and vibration issues in mechanical system. One is a software called DSS for motion and vibration simulation, which supports the sequence of operation of numerically solving the equation of motion and displaying the analytical results graphically. The other is an experimental teaching material, and we have already completed its around twenty experimental apparatuses with excitation device. In this study, we focused on manual excitation and developed two experimental apparatus of 3-DOF (three degrees of freedom) vibration system. One is a rectilinear vibration system, the other is a multi-type vibration system including pendulum, bending vibration and tortional vibration. In order to verify the validity of the equipment, each vibration system was simulated using DSS and compared with the experimental results.
