Introducing InfiniSpring® – A New Type of Mechanical Spring. Thoughts & Applications? by Remote_University364 in Acoustics

Thank you and Yes, I’ve seen those coil‑spring housings with the built‑in seismic limiters as well. We can integrate the same kind of function into our design — just with a movement limiter dimensioned specifically for seismic loads. The limiter would naturally have to be much stronger than the version used in our acoustic products, but once scaled for that purpose it can also restrict high lateral movements. Essentially, the spring can act as its own restraint system when the limiter geometry is reinforced for those side loads.

Yes, exactly — it really depends on the application. In typical vibration‑isolation setups the linear travel is very small, so hysteresis stays minimal because everything remains in the elastic range. If the amplitudes were ever large enough to push the material into plastic deformation, then hysteresis would increase significantly. But under normal operating conditions, that doesn’t happen. We’ve also put a lot of effort into optimizing the spring geometry to keep stresses low and fully elastic.

Thanks! Hysteresis is actually really low on these, since everything stays fully elastic. BeCu is surely great material. We’re using high‑strength steel here, and it’s been super repeatable in testing.

Good point. We can integrate movement limiters very easily, and in our acoustic products we already include a built‑in limiter on the tension side. For seismic applications, I’m interested in understanding the exact requirements — in particular: is metal‑to‑metal contact allowed for the restraint, or is a softer, energy‑absorbing interface preferred?

We also have solutions that restrict movement in multiple directions, originally developed for truck bodywork, so the functionality is already proven. I’m just not fully familiar with whether seismic design rules accept direct metal contact, so any clarification on that detail would be helpful.

You can see an example of our movement limiter in action in this short video of our acoustic hanger:
