Abstract

The invention discloses a CAE + CAD combined design method for turbomachinery. The method comprises the following steps: through one-dimensional aerodynamic design, three-dimensional models, three-dimensional numerical simulation analysis and finite element structure analysis of all parts of the turbomachinery are obtained, and drawings capable of being directly used for machining are obtained; based on a TurboTides integrated design platform and according to the three-dimensional geometric model obtained in the second step of the user, a CFD module and an FEA module are imported through one-key operation, whether the model meets the actual requirement or not is verified, the user can import the model into SolidWorks through one key, and detailed three-dimensional structures of all parts and two-dimensional drawings capable of being directly used for machining are generated. Compared with the prior art, the method has the following advantages: (1) unification of design software: effective management and integration of design data reduce interaction errors among software; (2) automatic detailed design: performing one-key CAD detailed design to generate a CAD drawing which can be directly used for processing; and (3) forming an effective design specification, wherein effective managers work cooperatively to form a unified specification.

Description

technical field [0001] The invention relates to the technical field of turbomachinery analysis and design, in particular to a CAE+CAD combined design method for turbomachinery. Background technique [0002] As an energy conversion device, impeller machinery obtains various powers for human society, and plays a very important role in aviation, energy, electric power, petrochemical, environmental protection, rail transportation and other fields. [0003] In the current turbomachinery design process, designers of many enterprises and research institutes use commercial CAE software to design turbomachinery components, and then export 3D geometric parameters or 3D models from the software, and then use commercial CAD software to design the various components of the turbomachinery. Carry out detailed structural design and complete the drawing of mechanical processing drawings. This process has the following disadvantages: [0004] (1) Scattered simulation tools: traditional desig...
