Numerical Simulation on Simplified Structural Strength of Engine Compressor Disk

Background:the compressor disk is an important component of the engine,the stress condition of the working environment is complex,its structure and performance will have a great impact on the engine.The purpose of this paper is to analyze the force on the engine disk,which is conducive to the optimization design of the disk structure,and then improve the thrust-weight ratio of the engine.The method of this paper:in this paper,theoretical analysis and finite element simulation are combined,and the theoretical solutions of radial and circumferential maximum stress are given based on the simplified structural strength of the disk under the assumption of symmetry.At the same time,the corresponding numerical simulation solution is obtained by using the finite element software ANSYS.The conclusion of this paper:the comparison between theoretical solution and simulation solution shows that the method presented in this paper can be used to solve and analyze the simplified structure strength of compressor disk.
