Multi-objective topology optimization method and system for lightweight design of power transmission tower

Abstract

The present application relates to the technical field of power equipment design, and particularly relates to a multi-target topological optimization power transmission tower lightweight design method and system, the method comprising: obtaining a topological structure of a target tower, a target function and a constraint function of a design target; sampling the topological structure to obtain an initial sample point set of design variables; constructing an initial surrogate model for the target function and the constraint function of each design target; obtaining a decision maker preference, and guiding the surrogate model to find optimal design variables based on the decision maker preference; and optimizing the topological structure of the target tower by using the obtained optimal design variables.
