The elements involved in the construction of a mini vibrating table (seismic table)?
Hi. For a mini shaking table, all what you need is:
- A stepper motor with screw axis.
- A Microcontroller like Arduino
- Some tools & craftwork skills
In fact, the same component list will be fine for a medium size shaking table.
A simple way to go some steps forward, is to use an old floppy drive or CD player.
In the file attched, you will find an example that I made for fun, using a 3.5" floppy drive device. Arduino is programmed to generate a random vibration. I think that this could be named a "mosquito shaking table"...
A CD a player is more suitable, because the piece that bear the compact disk is a table in itself.
To a bigger table, you can use the same principles: a stepper motor with screw axis (may be a CNC stepper motor) that can convert rotations to displacementes, and a controller to make it work as you want. The advantage of Arduino is that you can use it to retrieve lectures from accelerators and other measuremente devices, all at the same time.
I hope this will be useful to you, just ask if you need additional information.
@Juan Francisco Bissio I am grateful to you for your explanation, as soon as I start its Manufacturing I will come back to you for other ec pp explanations

I have not built a vibrating table, but I have worked with one, of the Quanser brand, basically they have the components mentioned by Juan Francisco, but instead of using Arduino microcontrollers, this vibrating table is controlled by an adaptation card between the CPU and the engines, and using Simulink using Matlab.
To ensure accuracy at the (desired) input, the moving part has an accelerometer whose response is compared in real time with the desired input to adjust the (real) input transmitted to the target; Since, due to the dynamic effects of the mass of the target to be mobilized, the input must be adjusted.
