Reliability Simulation Technology Research and Interface Development Based on Multiphysics Coupling and Physics of Failure

As an important part of reliability simulation, physics of failure simulation technology has been widely used in complex systems in aviation, aerospace, electronics, electromechanical and other fields in recent years. However, in the application process of current physics of failure simulation software, single physics simulation results are often used for calculation, which has a certain deviation from the actual conditions. After a thorough investigation of the multiphysics coupling simulation software and physics of failure simulation software, this paper developed an interface between the multiphysics coupling simulation software and the physics of failure simulation software based on a software called CARMES, which was independently developed by the Fifth Institute of Electronics of the Ministry of Industry and Information Technology. Then, a certain type of controller was used as an example for application verification. The verification results showed that the application of multiphysics coupling simulation helped to find more potential weak points and improve the credibility of the evaluation results.
