Problems solved by technology

[0003] In the existing technology, the engine is often evaluated only from a certain aspect of the parameters. On the one hand, the coupling relationship between the various operating components is ignored, and the process of the mutual influence of each component is not considered. On the other hand, the data is not collected comprehensively, resulting in Unable to comprehensively assess engine condition

Abstract

The invention relates to a marine engine state evaluation method and system based on digital twinning. The method comprises the steps: acquiring operation parameters and environment parameters of a marine engine; according to the operation parameters and the environment parameters, determining a working process model, a fault diagnosis model and a structural strength finite element model; establishing a corresponding digital twinborn model according to a parameter transmission relationship among the working process model, the fault diagnosis model and the structural strength finite element model; taking the operation parameters and the environment parameters as input of a digital twinborn model, and outputting corresponding evaluation parameters; and performing data processing according to the evaluation parameters, and determining and displaying the operation state of the marine engine. According to the method, the digital twinborn model is established to predict and diagnose the running states of the whole engine and the working parts, so that information fusion among various signals is completed, the coupling relation among the parts is fully considered, and more accurate and comprehensive diagnostic analysis is carried out.

Description
