Embodiment Construction
[0033] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0034] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0035] Such as figure 1 As shown, the vehicle drag coefficient optimization method based on the adaptive proxy model includes the following steps:
[0036] A. Carry out CFD simulation calculation on the initial model of the car to obtain the calculated value of the drag coefficient of the initial model;
[0037] B. Select the design variables and determine the variation range of the design variables;
[0038] C. Construct a parametric model based on the initial model;
[0039] D. Select a sample point and store it in the sample point database;
[0040] E. Calculate the drag coefficient calculation value corresponding to the sample point based on the parameterized model, and store it ...
