Abstract

A failure criterion determination method based on function analysis and mechanism analysis includes a first step of carrying out system level division on products and determining fault bodies of the products at the lowest level and functions of the fault bodies, wherein the 'system level division' refers to the fact that a system is divided into subsystems and components in sequence until smallest analysis units, and the 'lowest level' refers to the fact that the lowest level which can meet technical requirements, a second step of searching possible failure modes and failure mechanisms according to failure mode impact analysis and consultation of expert opinions, analyzing related relations between the failure modes and the failure mechanisms, and building correlation matrixes of the failure modes and the failure mechanisms, and a third step of carrying out classification specific to different function decay modes, combining the established correlation matrixes of the failure modes and the failure mechanisms in the second step, inspecting whether the failure modes are measurable, and determining the failure criterion after classification and corresponding measurability analysis are finished. The failure criterion determination method is wide in applicability, capable of obtaining the appropriate failure criterion, and good in application value.

Description

technical field [0001] The present invention provides a method for determining fault criteria for functional analysis and mechanism analysis, which is based on the functional analysis and mechanism analysis of products respectively, and proposes a systematic method to determine fault criteria, which belongs to fault study and reliability analysis , comprehensive safeguard analysis and other related technical fields. Background technique [0002] Before predicting, formulating, and evaluating indicators such as a product's quality or reliability, it is usually necessary to collect, accumulate, analyze, and process relevant fault data information. Fault data exists in the work and activities of each stage of the product life cycle. It describes the state of the product that cannot complete the specified function under the specified conditions at the specified time, and has time complexity and space complexity. [0003] However, in the current model development process, the pr...
