Abstract:
An educational model (shaking table) designed and implemented to simulate the effect of
the harmonic motion on structural and mechanical systems, where various frequencies can be
applied on different structures whence weight , the properties or material type, and in our study the
structures located above the shaking plate ,a structures consists three mass equal on weight and type
of material but each mass the height from table is different
The shaking table will be provide to PPU laboratories to enhanced the understanding of the
effect of vibration on structures and demonstrate the resonance phenomena and pre- and postresonance
phenomena and comparison between theoretical and experimental result .
The harmonic motion of the shaking table will be generated by stepper motor which
moves a mechanism (slider with two gear and timing belt ) and the system controlled by an Arduino
Uno and Arduino Nano, the various frequencies generated by three Potentiometers.
