Embodiment Construction
[0064] Combine below Figure 3-Figure 10 The present invention will be described in further detail with specific examples.
[0065] refer to image 3 In , the general flowchart of the optimization algorithm for the surrogate model includes the following steps:
[0066] Step 1. Obtain the design features of the offshore support structure and screen the design variables through engineering project experience. In the present invention, the design variables are the diameter of the tower bottom and the diameter of the single pile;
[0067] Step 2, adopt sampling method to generate initial sample set in the design space, the present invention adopts central compound test method;
[0068] Step 3: Perform numerical simulation analysis on each sample point in the initial sample set to obtain the corresponding structural performance response. In the present invention, the structural performance response is the mass of the tower, the mass of the single pile and the frequency of the ove...
