Abstract :
One of the equipments that is widely used today in buildings with four floors and more is the elevator. Therefore, it is important to study different aspects of the elevator. On the other hand, one of the studies that has become important in most systems, including the engineering system, is the study of reliability. Reliability means how well a system can perform its function correctly. Therefore, the purpose of this article is to study the reliability of the elevator. To determine the reliability of the elevator, it must first be determined what equipment this system is made of. Then the effect of failure of each component of the elevator on the failure of the whole system is studied and finally the reliability model of the elevator is obtained. In this article, the reliability model of two widely used types of elevators, including traction and hydraulic elevators, is obtained based on the effect of failure of basic components. Also, in order to check the reliability model of elevators, simulation has been done in MATLAB software environment.
