Experimental verifications of control effects for severe conditions at elevator emergency stop based on the safety standards

Abstract

The number of skyscrapers may be one of the barometers in showing the economic power of the country. Such powerful countries continue to build high-rise buildings with various facilities for comfort and safety, based on advanced technologies. As transportation means in such buildings are mainly elevators, the strict “Safety Standards” for them are provided. It is because the elevators in the high-rise buildings have large potential energy enough to take away the lives of elevator-passengers. “Emergency Stop Device” for speedily stopping the elevator is a key item to save the lives. However, because of the impact force received from this device at the sudden emergency stop, many injured people are occurring at present. In our previous papers, we proposed an emergency stop device with a semi-active magneto rheological fluid damper to soften the impact force at an emergency stop and showed its effectiveness by digital simulations. In this study, by using a small size elevator apparatus, we will perform many experiments to verify the effectiveness of our proposing control, based on EN and JIS Standards.
