Reliability and Safety of Vertical Transportation Use

Abstract

At present the problem of vertical transport safety is crucial as it is evidenced by the statistical data on the number of accidents and injuries There are no regulatory requirements for permissible safety level of the elevator performance. service support system for the elevator is aimed at maintaining the performance standard level throughout the specified service life of vertical transportation. For the elevator equipment which is a technically complex system, hazard is manifested in the form of failure of various structural elements that affect safety. In this study the probability of a hazardous situation is characterized as risk-failure.

Properties of the rubber vibration isolator of the elevator

“…In all cases, useful, and sometimes decisive, may be an increase in the damping properties of the dynamic system. With regard to the passenger elevator, we note the importance of the damping properties of the system in resonant zones, even if there is only a danger of passing through resonance at a certain number of storeys of buildings [3,7,8,9,12,13]. Especially we can say about high-speed elevators in high-rise buildings: there are noticeable fluctuations in the elevator car not only in the vertical plane, but also in the horizontal plane.…”
