This is inspiring. What an exciting field this is. I am not an engineering student. I'm a psych grad student yet my keen interest in this field stems from my trying to solve a movement/vibration problem on a 6DOF sim racing motion platform (my new sober hobby - there will be a RU-vid channel) for which has both actuator movement and haptic vibration that needs to be isolated. I'm going to reach out to some people in the academic world and hope they might be able to advise me! So, expect to hear from me, Professor.
Great video and presentation. How can I get this product? Or the specs to print my own? Because our site needs this to stabilize wall mounted cameras and nothing else works adequately.
Congrats on your great work. I wonder how you solved the equation of motion in the y-direction, Equation S16, to find the isolation results in the frequency domain, please. I mean whether you used Simulink since it is a nonlinear function or any other method.
Very interesting experiments!!! But, could you tell me some differences between conventional QZS mechanisms and yours? If you do so, then the originality of your research will get much stronger.
I have a question regarding the horizontal shaking test. Wouldn't the random shakings from the two shakers cancel out yielding a smaller effective shaking?
No, if they're un-correlated then you'd expect the resulting vibration to have a magnitude larger by a factor of the square root of 2. Sometimes they cancel, sometimes they combine, but overall its an increase in vibration.
@@Kruglord You are right. I think the sqrt(2) factor is for Gaussian noise though, for uniform random the factor is more like 1.33 (at least that's what i find numerically)
A lot of those things don't make sense to me. There is a negative transmissibility but that is into a number that can be negative. It seems to me like they just created a low frequency isolator.
