Is it really impossible to solve those oscillations? If the spacecraft is being shaken so severely that people cannot see, then surely other designs are being i

  This is a common issue with solid rockets - they vibrate a lot. There are payloads that are suitable for, say, Falcon 9 that can't fly on the SLS because of the SRBs. Other fixes were employed to avoid the entire rocket to enter resonant vibration (IIRC, resonant frequency of the solid rocket was something around 12 Hz and with the fueled upper stage at 14 Hz, it was too close for NASA's comfort). A series of vibration dampers were added to the booster skirt and, something, I don't remember what, but probably another set of dampers, was added to the interstage. Ares I was, to put it simply, a bad design. By the end of all this, NASA decided, correctly, to ditch the idea.
