Оптимизация лопатки рабочего колеса турбокомпрессора по критерию собственной частоты колебаний

Abstract

The optimization problem for blade of the turbocompressor for internal combustion engine boosting turbine wheel is solved. The objective function is the first natural frequency, variable parameters are blade thicknesses in FEM-grid nodes. 2D shell model of blade with triange finite element is used. We use the modification of the quazi-Newton optimization method with BFGS-formula, cube approximation in the 1D search and sliding along boundless. Numerical results are presented
