Problems solved by technology

In the one-dimensional cooling system simulation model built, there are a lot of input parameters, and the effect of CAE simulation is lost only by manual input and round-trip attempts by engineers.
[0010] At the same time, it is not easy to find the parameter with the largest impact factor among many input parameters, and the impact is often caused by the combination of multiple parameters. It is difficult to find the optimal solution when re-executing steps (1)-(4)
In addition, it is difficult to find innovative solutions under the single operation of engineers

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an optimization simulation calculation method for an engine cooling system. Background technique [0002] The cooling system is an important part of the engine. A well-designed cooling system can ensure that the power plant and related components operate under ideal conditions, such as no overheating, rapid warm-up, constant temperature or strict temperature under all operating conditions range of change, etc. [0003] During the engine development process, the bench test of the engine cooling system must not be carried out until the prototype is completed. At this time, if it is found that the layout is improper and unreasonable, many modifications are not easy to implement, which increases the difficulty of optimization. Therefore, it is very important to predict and optimize the performance of the engine cooling system before the prototype trial production. [0004] The step...
