Abstract
A method and system for constructing component fault tree based on physics of failure are disclosed. The method includes the steps of: establishing, based on common characteristics of component physics of failure and according to six layers based on physics of failure and category of the component, a fault information database containing information of the six layers based on physics of failure; constructing, based on the fault information database and according to the six layers based on physics of failure and logical relationship of physics of failure, a component fault tree of n levels of events of six layers based on physics of failure; and simplifying the fault tree by means of failure mechanism sub-tree transferring and fault module sub-tree importing. The method and system are applicable to construction of fault tree of various components.
