승강기 과부하 감지용 방진고무의 수명예측과 검증

Abstract

By the end of 2008 in Korea, there are more than 380,000 elevators in operation and elevators are increasing more than 20,000 elevators every year. The better services of maintenance has been highly needed due to the demand of users and the expand of elevator industry and it is axiomatic that users require higher level of satisfaction. The rubber psrts, one of the elevator's parts for reducing vibration, is responsible for ride quality and safety by detecting overload. ① Safety could not be satisfied by only the inspection code. So these reasons, it is almost impossible that meet the better services of maintenance ② The relationships between compression load and displacement vary according to time, so it includes potential risk ③ It is almost impossible to maintain by the high quality service because the alteration period has not been decided, also the practice or concept about components life have not established rightly. Rubber material properties and useful life evaluation are very important in design procedure to assure the safety and reliability of the rubber components. In this paper, the evaluation of characteristics and useful life prediction of rubber component for elevator cabin were experimentally investigated. By using the rubber material and component test several useful life prediction equations for rubber component were proposed. Predicted useful life of rubber component for elevator cabin agreed fairly with the experimental lives.
