World's Fastest Elevator is Also the Smoothest

Posted April 02, 2015 12:00 AM by Engineering360 eNewsletter

When China greets its soon-to-be tallest building, patrons taking the elevator to the top of the 119-story structure will like what they don't feel. The ultra-high-speed elevator can reach speeds of 40 mph, but its new active roller guide system makes the ride smooth. Made up of nine vibration sensors, the guide system cancels motion by applying force in the opposite direction of the vibration. Simulated tests showed that without the guide system, patrons would be tossed about in the lift car, but with the system in place, no movement at all.

No wonder they don't feel anything. No movement at all is the perfect solution to that, if not to transportation.

! GA!

How does one attain no movement at all with a velocity of 40mph?

I have been in many buildings and inside hydroelectric dams with high speed but much slower than this. Many have extremely smooth operation, with no side to side (lateral) movement and many have acceleration rates which are barely detectible. However, I have always had a problems with the rate of elevation change which many find a problem for their sinuses. At 40 MPH that will be a real problem for many humans. A short burst of higher speed like on a roller coaster is fine, because it a short distance, but if someone goes the full distance from bottom to top without stops, they may have trouble with ear-popping and sinus due to elevation change. I wonder if they took this into consideration?
