Hi all, I took a few minutes to build a non-working horizontal response model of what I think a 3 wire "x" suspension could look like. Am trying to grasp such. I don't know if its even ~ practical actually. I would think it could have unidirectional horizontal response. Its seemingly more likely to instead have the mass underneath the bottom "plate" for perhaps better period adjustment range. See: http://seismometer.googlepages.com/3wirexsuspension New and "strange" yes, but interesting. The trouble with this is that I don't think anyone has actual experience...but if they do; I'd like to hear about it.....or.....any comments....
