Abstract

To find the failure propagation mechanism from the inherent topological structure of the complex electromechanical system

the topological structure statistical properties of the system were analyzed with small world net theory

and a failure propagation model based on the small world clustering was proposed. Subsequently

the grade diffusing process was described combining with the failure pervasion intensity

and the failure propagation paths and relevant key nodes with high pervasion ability were found with the ant colony algorithm. An applied case of injection engine was provided to illustrate the feasibility of the proposed model in failure propagation analysis

and to verify the efficiency to find the system crisp nodes which become the proofs for the design improvement and failure prevention.
