A friend of mine asked me why their new Duet Sport seems to vibrate an awful lot on the slower speeds, but then seems to stabelize once it reaches the higher. That sparked a question from me to everyone here. I get that the machine vibrates more on slower speeds, and when it begins to reach higher speeds, it starts vibrating so hard that the vibrations cancel each other out and the machine is stable. But, at what speed do most front loaders seem to stabelize?

Resonant frequency I've seen my Frigemore do this. Apparently, the suspension system seems to have a natural frequency when the tub is spinning at the right rpm, the it will cause the whole thing to vibrate and as the tub goes beyond that certain frequency, it begins to settle down. | ||

It's not just to do with vibrations, but resonance frequency as well. I think a lot of flooring materials seem to have a resonance frequency that corresponds with the frequencies produced by the washers at around 900-1000rpm, at least in my experience. | ||

IMHO vibrations during spin cycles are more the result of unbalanced loads than anything else. When loads are in perfect harmony in my Miele, there is no sounds during the final spin other than the soothing "jet engine at full throttle" sounds. However if a load is unbalanced there will be some shaking/vibrations. How much will depend upon how unbalanced. My vintage Miele is not as picky as many of today's newer machines about unbalanced loads and spinning. While have yet to cause any harm, or cause the machine to bounce around the room, it sill will rise to the occasion and get the job done. Simple laws of physics dicate if there is more weight on one side, the tub is going to pull towards that direction. That beind said, have stood near 50lb laundromat Speed Queen washers, and on a full load say of heavy featherbeds, you can feel the vibrations coming through the concrete floor from the machine. This even standing several feet away from the washer. L. | ||
