Abstract
Recently, the case that a stairs elevator is installed on from the 1st floor to the 2nd floor has been increasing along with the fulfillment of the welfare machine. This paper describes the preliminary investigation of the vibration control to secure the comfortability of a stairs elevator. A stairs elevator is considered as a movement body restrained on the three-dimentional orbit. The response vibration at the seat in the top-bottom, front-back, and left-right direction is analyzed taking the stiffness, the damping etc as parameters, and these effects are investigated.
