摆动活齿传动系统故障树分析

Abstract

The general method of the fault tree analysis of swing movable teeth drive is investigated in this paper.The fault tree of swing movable teeth drive system is built up,and its structure function is presented. A calculating method of the reliability of the movable teeth drive system is established and analyzed. The probability of event occurrence in a movable teeth drive is described by fuzzy number. The fuzzy fault tree analysis of a swing movable teeth transmission system is conducted.
