Spring and Damper system for viabrations

Click For Summary

Discussion Overview

The discussion revolves around understanding the vibration effects caused by two servo motors moving 75 KG masses on a granite countertop. Participants explore the application of spring and damper systems in modeling these vibrations and seek to clarify the specific nature of the vibration effects in question.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant suggests measuring vibrations with accelerometers to gather data on the granite countertop's response.
  • Another participant emphasizes the need for clarification on what specific "vibration effects" are of interest to provide useful assistance.
  • It is noted that vibration studies typically involve modeling systems as "spring-mass-dampers," and a diagram of the setup could enhance understanding of the problem.

Areas of Agreement / Disagreement

Participants express a need for more information and clarification before proceeding, indicating that the discussion remains unresolved and multiple viewpoints are present regarding how to approach the problem.

Contextual Notes

Limitations include the lack of specific definitions for "vibration effects" and the absence of visual aids to illustrate the setup, which may hinder the ability to provide targeted advice.

Hi,

This is a real life problem I am trying to find vibration effects.

I have 2 servo motors constantly going back and forth on a granite countertop. The two servo motors are moving two 75 KG masses.

I am trying to solve for the vibration effects that will happen on the granite countertop and all I read about is mass damper systems.

Is there a spring and damper value that I should assign to the granite table?

How do I solve the problem?

printzOr, So you want to find “the vibration effects that will happen”! I cannot tell you how to predict (solve) for them.

You might consider measuring the vibrations of the granite countertop with accelerometers, for example.

Cheers,

You need to explain what "vibration effects" you are interested in, before you will get much useful help here. Some diagrams or photos of the setup might be useful to explain what the problem is.
 
Vibration studies are accomplished by modeling systems as "spring-mass-dampers." However it is vital to provide a diagram of your setup to see exactly what your talking about.
