Abstract

The advent of verticalization after WWII made the densification of major cities. Thus the high-rise building was the solution to accommodate the vast amount of people in cities. The elevator was a solution to the vertical transport of cargo and people. However, safe, fast, and stable travel it a basic requirement to ensure a good public perception. Even, on extreme cases of a high building, high speeds on the seismic region. The high-speed elevator are subject to high impact and must stabilize the motion. In this paper, a mathematical model of elevator with a cubic spring with a big impact is used to destabilize the motion. The dynamic of the elevator is determined to reduce the motion varying the angle of the rollers and the excitation frequency. The results show a jump on the motion when the phase angle is different than $180^{\circ}$. In addition, the chaotic region can be controlled with a pneumatic actuator and reduce the general displacement.
