Research on Reliability Evaluation Technology Based on Digital Heterogeneous Model Simulation
With the rapid development of new electromechanical systems in terms of advance-ment and functional complexity,the system structures gradually evolve towards modularization and networking.In view of the deficiencies in the means of system reliability assessment and the ac-quisition methods of component failure rates in the current design process of complex electrome-chanical systems,a reliability prediction method for complex electromechanical systems based on simulation analysis is proposed.This method uses digital heterogeneous model fu-sion simulation,and employs the simulation flow to divide the complex electromechanical system into system modeling and component modeling.Referring to the model based systems engineering concept,system modeling is carried out for the complex electromechanical sys-tem.And combined with component physical simulation modeling,reliability models such as the probabilistic life model are obtained,so the proposed method is validated throgh ex-amples,and the reliability level of the complex electromechanical system is predicted quickly.Finally,the verification is conducted through examples,and the results show that the proposed method can quickly achieve the preliminary assessment of reliability indicators.
