Problems solved by technology

[0003] In the prior art, the engine model used in the engine development process is to input the test data to the basic model to generate the target model, and simulate the target model, but when the test data is obtained, generally only the engine test data Parameter calibration, which leads to defects in the input data or the accuracy cannot meet the test standards, resulting in the need for repeated model calibration work, which in turn leads to a longer development cycle

Abstract

The embodiment of the invention provides a method for virtually calibrating an engine model, which is used for improving the precision of a calibration value of the engine model so as to reduce the workload of calibration work. The method comprises the steps of obtaining test data; acquiring a basic engine model; acquiring a combustion analysis data sample of the engine according to the test data; performing model training on a cylinder model of the basic engine model according to the combustion analysis data sample to obtain a target cylinder model; generating target cylinder calibration data according to the target cylinder model; calibrating a cylinder model of the basic engine model according to the target cylinder calibration data; calibrating the sub-model precision of the basic engine model according to the steady-state test data; operating the calibrated basic engine model to generate operation data; judging whether the precision of the sub-model in the operation data accords with preset precision or not; if yes, calibrating a temperature sensor of the basic engine model according to the transient test data, and forming a target engine.

Description

technical field [0001] The embodiments of the present application relate to data processing, and in particular to a method for virtually calibrating an engine model and related devices. Background technique [0002] In the process of engine research and development, simulation test is a method to save development cycle and development consumption. [0003] In the prior art, the engine model used in the engine development process is to input the test data to the basic model to generate the target model, and simulate the target model, but when the test data is obtained, generally only the engine test data Parameter calibration, which leads to defects in the input data or the accuracy cannot meet the test standards, resulting in the need for repeated model calibration work, which in turn leads to a longer development cycle. Contents of the invention [0004] The embodiment of the present application provides a method for virtual calibration of an engine model, which is used ...
