Abstract

<p>　Recently, the number of skyscrapers is increasing in the countries with rapid economic growth. From its background, hi-speed, safe and comfortable elevators are demanded. However, in an elevator emergency stoppage, the large impact force from an emergency stop device injures passengers. Additionally, in a normal operation, the vertical vibration caused by the spring component of lifting wire deteriorates ride-comfort of an elevator. In order to reduce the impact force in an emergency stoppage, we had proposed a new structure of elevator with a magnetorheological fluid control damper by utilizing elevator’s double-cage structure. In this paper, we would like to design new controllers for reducing impact force and apply our system to improve ride-comfort. Then, we would like to verify the effect of our system from viewpoints of comfort and safety for passengers by many digital simulations with MATLAB/Simulink.</p>
