Abstract

This work investigates the lateral and rotational displacements of a high-speed elevator. Numerical simulations are performed for a mathematical model with two degrees of freedom. The lateral and rotational accelerations are analyzed for different travel speeds to determine the passengers' comfort levels. To attenuate elevator vibrations, the replacement of the linear spring of the elevator roller with a spring composed of shape memory material (SMA) was considered. The influence of spring stiffness with SMA is investigated for different temperatures and vertical travel velocity of the elevator. The numerical results demonstrated that the elevator reduces the lateral and rotational accelerations for certain vertical travel speeds, that the spring with SMA influences the elevator vibrations, and that it can be considered a semi-active vibration control system.
