Abstract

The invention relates to the field of compressor rotor systems, and provides a dynamic characteristic optimization design method of a centrifugal compression rotor system considering the aerodynamic force, in particular to an optimization design method of an impeller rotating subsystem. According to the method, a more complete design structure is considered, DOE experimental design, fluid-solid coupling simulation analysis, a Kriging agent model and a non-dominated sorting genetic algorithm are combined, and rotor system design is carried out. According to the method, the specific structure in the design model is deepened, the accuracy of model calculation is improved, the robust optimization design workload is reduced, the working efficiency is improved, and an important reference is provided for impeller rotating subsystem design.

Description

technical field [0001] The invention relates to the field of compressor rotor systems, and provides an optimal design method for dynamic characteristics of a centrifugal compression rotor system considering aerodynamic force, in particular an optimal design method for an impeller rotor system. Background technique [0002] As far as the centrifugal rotor system is concerned, most of the current research focuses on a single centrifugal impeller or shaft as the design research object. At present, there are almost no situations in the market and academia that take the entire centrifugal rotor system as the research object. [0003] In the design of the centrifugal impeller as the research object, the isentropic efficiency and pressure transmission ratio of the impeller are taken as the goals of design and subsequent optimization, and part of the structure of the impeller is improved. In the design research with the rotating shaft as the research object, they dealt with the impe...
