Hi Hotfix,
When fleshing out my last answer, I realized that there would be more to be said in order to provide some more meaningful assistance. For that to be effective I needed to invest a little bit more thought. Fortunately, @Tarrant1702 also posted some very nice links which got me thinking and @matcoland and @drakko confirmed that there was some wider interest. Of course, the recent sharp increase on vibration insulator models (some more, some less effective) on MakerWorld showed me that some further insights may also be helpful to the wider community.
Three main items came to mind:
- Although @julie777 very nicely explained the importance of mass, the reason why seems to be easily forgotten
- The importance of spring stiffness does not seem to be so well understood
- At a certain point, considerations narrow down on damping rather than thinking more freely about energy conversion
=> The general discussion seems to be stuck at Vibration Isolators: It is only a very small step to true Vibration Absorbers.
My very simple design is not a be-all and end-all. It is only of a very first, self-teaching step: Hopefully the needed push to go to true Vibration Absorbers from better designers than myself.
The pads can be printed in TPU purely for supervised experimentation and I provided a more detailed insight in the description. That should be able to take you all the way from double checking your Vibration Insulators, see why to place the paver where and to being able to play around with a very simple but true Vibration Absorption. Regarding vibrations: Feeling is believing.
It also gave me a chance to make a first experience with MakerWorld myself. Not being much of a designer, I have wanted to try it out for a while. Let’s see how that goes.
I do hope that you find it useful or at least interesting. Furthermore, it may actually help us in getting better vibration insulators and of course that we do get actual vibration absorber solutions from the community.
Merry Christmas,
Eno
PS: Please do not feel obliged to actually run through the experiment just because my post is adressed to you. You got me thinking and I needed to work that out this far for my own well being.
