The article considers the problem of optimal design of a mesh cylindrical structure. Such

structures are widely used in the aerospace industry. Optimal design of these structures al-

lows increasing the efficiency of their use, minimizing the mass, while observing the condi-

tions for strength and stability. The formulation of the problem of mesh construction optimal

design in general form is given. The application of various optimal design algorithms using

known analytical dependencies is considered. The optimization algorithm is based on the

simplex search method, where a partial R-predicate of the admissible domain is used to de-

scribe nonconvex smooth boundary sections. The results of solving the optimization problem

for a particular design by various methods and the results of calculating the stress-strain state

of the corresponding models are presented. The discrepancies in the results are due to the

different set of constraints used in the methods in question.

Keywords:

optimal design of structures, mesh cylindrical structure, minimum mass,

strength, stability, optimization algorithm, R-functions
