Abstract

Abstract: The reliability of the motion mechanism for automatic door is the key factor for usability of vacuum equipment. Aiming at the motion mechanism for new type of automatic door, based on the FMEA, the failure tree model of motion mechanism was established and the minimal cut set was analyzed. The fault tree was analyzed qualitatively and quantitatively. The weak links affecting the system reliability were found out and the suggestions were proposed in this paper.

Key words: reliability, FTA, motion mechanism, importance analysis
