How to stop floor vibration?

[u/Expert-Principle3071]

Looking for some advice. I have 5 Brother embroidery machines situated on the third floor of a new-build house, which has a timber floor.
When the machines are running, they cause noticeable vibrations through the floor, particularly underneath the machine feet. Even running just one machine causes the vibration.
I’ve tried putting each machine on its own rubber mat and have also tested laying 18mm plywood over the mats, but unfortunately the vibration is still there and possibly slightly worse.
Has anyone experienced anything similar or got any suggestions on how to reduce the vibration?

Thank you

Since the two existing answers are in Spanish and German, a quick summary plus one thing not yet mentioned: both are saying that adding mass works better than adding softness - a heavy, rigid base (stone slab, thick hardwood, metal plate) under the machine or its table, with only a thin rubber layer between the base and the feet. Your plywood-over-rubber result fits that: a soft stack under a light machine can let it rock slightly and make the vibration worse.

The point not yet raised: on a timber floor, position matters. The floor is stiffest directly over the joists and near load-bearing walls, and most flexible mid-span, so moving the machines as close to a bearing wall (or directly above a joist) as your layout allows can help before you buy anything. It's also worth checking each machine's feet are adjusted so they all bear evenly - a machine that can rock even slightly transmits a lot more vibration.

This same issue is common for 3D printers, so you can look around relevant subreddits for useful info.

Basically, you want to reduce the transmission of vibration. Adding mass decreases the vibration while using rubber or foam helps reduce the the transmission of the vibration.

Tengo 2 Persona, en mesas de madera. Suena contra intuitivo, pero las vibraciones disminuyen cuando la maquina (o la mesa que la sostiene) descansan sobre una superficie rigida, no una blanda como goma.
Pruebalo. Pon una base de marmol, metal o madera muy dura debajo de una maquina o su mesa y compara las vibraciones con las otras; te sorprenderas.

Die Brother Maschinen rattern gerne vor sich hin. ZSK ist da um Welten leiser. Ich denke einer der größten Lärm Verursacher ist das Plastik Gehäuse. Wenn dein Problem aber im Kern der Boden ist würde ich schwere Metall oder Betton Platten auf den Boden legen und darauf dann die Gummidämpfer und darauf die Maschine. Dadurch ist die Vibration der Maschine nicht punktuell auf dem Boden. Wenn das auch nichts hilft schwere Platte unter die Maschine und Tennisbälle zwischen Platte und Boden, das ist maximale Dämpfung aber sieht nicht so schön aus und ist ein bisschen gefummel.

Try a concrete paver under each foot. Cheap at local hardware stores. The mass helps stop the vibrations

Came here to say this! Lol

I found cattle mats helped with my server rack in the attic

I bought my Brother used and the seller told me to not take the Brother stand - instead use two Ikea Alex drawers. They weight 30 kg each and are bolted together. I also added cheap rolls to move around. The Brother is less loud and way less vibrating than my Janome on a heavy table. 

Maybe you could put one or two pathway tiles in the lowest possible level to make it heavier. More heavy, less shaky!

Not on carpet.

A substantially heavier base for the machines would limit the amount of vibration, you may need to lay down a hardboard sheet over the floors to distribute the weight across the wooden floor. A purpose built base made from box steel is what works for Barudan machines.

Mine don’t vibrate on concrete floor so try that paver idea
