【 摘 要 】

The purpose of the study was to find the optimal configuration of the main parameters of the reinforcing layer of a compressor wheel made of composite material. The optimization problem for an anisotropic system was solved using the Gauss-Seidel method. According to the results of calculations, it was established that under the condition of preserving the strength of the wheel, there is the possibility of transition to reinforcing layers in which the fibers are oriented only in the circumferential direction, which makes it possible to significantly simplify the technology of its manufacture. The use of reinforcement for compressor wheels made of composite material can significantly reduce its mass and polar moment of inertia, which contributes to the improvement of strength and performance of the turbocharger and the engine as a whole.
