Elevator Safety AssessmentБайду номын сангаасBased on Risk Analysis
ABSTRACT
Elevator is a vehicle closely related to people’s daily life, yet sometimes it incurs safety problems. Nowadays the society is demanding stricter safety requirements on elevator system. And new technologies are being developed and applied to elevator system. As a result, there are some new concerns with elevator’s safety: first, the conflicts between the new safety code and the large number of elevators in use; second, peoples’ increased dependence on elevator; third, new safety criteria and safety concepts for new technologies. Therefore, developing new methodology for elevator safety assessment is very important.
The research in this paper mainly includes four parts: Firstly, the safety assessment method for elevator system on basis of

ABSTRACT
risk theory is obtained, which contains the thoughts of many other kinds of safety assessment methods. The target of comprehensive safety assessment for elevator is reached after applying the method.
At the same time, the developing of expert system and database technology can support the intelligentize in safety assessment for elevator. Designing the expert system of safety assessment for elevator and establishing the repository for the system are achieved in this paper. The system can learn knowledge from experts, provide knowledge for users.
Combined with project of the eleventh five-year plan for research on safety technology of special equipments, a safety assessment method for elevator system on basis of risk theory is obtained in this paper after referencing many kinds of safety assessment methods. The method contains the thoughts of these methods, such as fault tree, fuzzy evaluation and safety checklist analysis. The target of comprehensive safety assessment for elevator is reached after applying the method.
Secondly, the database for elevator safety assessment is established. The database is made up of parameter database, safety requirement database, danger and risk database and protective measure database.
