Method for predicting engine performance parameter modification amount and related device

Abstract

The embodiment of the invention provides a method for predicting the modification amount of engine performance parameters and a related device. The method and the device are used for predicting the modification amount of an engine supercharger. The method comprises the steps: obtaining an engine model; acquiring a supercharger data sample, wherein the supercharger data sample is obtained by permutation and combination of all data in the supercharger efficiency range interval and all data in the supercharger flow range interval; respectively substituting all data in the supercharger data sample into the engine model to generate a test engine model group; respectively operating the test engine models in the test engine model group to obtain performance parameter data; analyzing and calculating all the performance parameter data to obtain a calculation result; identifying a target parameter which causes the performance parameter data not to reach a preset performance parameter data standard according to a calculation result; and comparing the target parameter with a target parameter in a preset performance parameter data standard of the engine model to determine a modification predicted value of the target parameter.

Description

Technical field[0001]The present application embodiment relates to the field of simulation simulation, and more particularly to a method and related apparatus for predicting engine performance parameters modifications.Background technique[0002]In the actual situation, the performance will meet the development goals after the engine development is completed. However, in actual production, there is often a case where performance changes or large absence, causing engine performance to meet preset needs.[0003]In the prior art, in order to reduce this problem, it is often a quality control of the quality of the parts, but it cannot be specifically controlled to control performance parameters, so that accurate response measures can not be rectified, resulting in the engine when producing Ruilant risk.Inventive content[0004]The present application provides a method and related apparatus for predicting an engine performance parameter modification for predicting the modification of the engin...

Problems solved by technology

However, in actual production, performance changes or large dispersion often occur, resulting in engine performance that cannot meet the preset requirements

[0003]In the existing technology, in order to reduce this problem, it is often to strengthen the quality control of the quality of the parts, but it cannot be specific enough to control the performance parameters, so it cannot be adopted Accurate countermeasures for rectification, resulting in compliance risks in engine production
