    Seismic isolator based on magnetic forces

    sorry, can't make more lab test as they tell me that the ones i have already should be in off to make the model, nevertheless i made an extra test for an specific earthquake:

    Seismic isolator based on magnetic forces

    hi, sorry for not replying in this long time you say a single frequency in the lab?

    Seismic isolator based on magnetic forces

    hi, in these days i have been testing an new approach of the damping force (eddy currents) as i found it is linear in almost static cases which is not my case. my old approach was: $$ F_d=c \cdot U' $$ my new approach is: $$ \frac {0.5} {0.5 - \sqrt { U'}} \cdot c $$ mulltiply by the sign...

    What is the potential of using magnetic forces for seismic isolation?

    hi, i am back, i just opened the trhead: https://www.physicsforums.com/threads/seismic-isolator-based-on-magnetic-forces.872369/ tell me if that vacation travel goes around :D

    Seismic isolator based on magnetic forces

    Hi, i am an student of civil engineering and i am doing my graduate thesis. so sorry if i misspell, english is not my native languaje. so, here we go :D Homework Statement Before entering in details you (whoever you are) most know: The system is scaled for obvious reasons. The system consists...

    What is the potential of using magnetic forces for seismic isolation?

    i think answering you question goes against the introduction myself thread rules :v, anyway it is a engeenering topic with very specific physics topics (seismic isolator with restoring magnetic force). I am making the thread lucking for luck if anybody could help.

    What is the potential of using magnetic forces for seismic isolation?

    hi, thanks for replying. right now is quite a good moment to visit my conuntry, exchange rate can make it happen cheap. your guess was right i am a undergraduate student in the last period of the career, which is thesis :v
