Aiming at the optimization design of the support beam of wind turbine blade glass fiber fabric laying equipment,a single-particle optimization algorithm for two-parameter was proposed to optimize its structure.Firstly,the optimization direction and step size of the single-particle were set up,and the optimization mathematical model was constructed.With the degree of stress dispersion as the optimization objective,the optimization of two-parameter was achieved by single-particle optimization.Finally,the topological simulation and field test of the support beam was done.It will be seen from the results that the optimized model of support beam can achieve stress dispersion in a better way,and the deviations of the layer are within the allowable range of structural design.This study validates the feasibility of single-particle optimization algorithm for structural optimization and provides theoretical support for subsequent optimization engineering applications.
