namsan cable car vibration control device(TMD) installation and performance test results
TESolution, with the goal of controlling the wind vibration, installed vibration control devices(pendulum type TMD) on Namsan cable cars(two vehicles). Our target goal was to the reduce wind vibration by 40% at the 1st tower and after the performance test, we found out that wind vibration indeed was reduced by 40 ~ 60 %. We expect that this result will contribute in structural safety and pleasant ride environment from wind vibration.
