英文摘要: |
In view of the problem of unknown components at service condition, an adapting method based on the rig data was proposed
to obtain the characteristics of the engine components under the actual condition. Adjustment parameters were selected based on the
analysis of model characteristics and test data. The error of model simulation and test data was selected as objective function and used in
iterative algorithm for component characteristics. The simulation results show that the error between the model simulation which derived
from the method and test data is within the maximum error. The components characteristics was obtained by using the engine matching
technology based on the test data, which provide support for engine simulation and prediction under the actual condition. |
