Problems solved by technology
[0005] The disadvantages of the above-mentioned existing scheme design methods are: 1) It takes a long time for the designer to manually draw the pipe network topology model, which affects work efficiency; 2) The manual operation increases the possibility of errors; 3) The manually drawn network diagram splits The connection between the geometric unit and the geometric model cannot automatically update the geometric unit data with the change of the geometric model, so the calculation cycle is increased, making it impossible to achieve multiple rounds of design iterations within a limited time

The invention belongs to the technical field of aero-engine turbine cooling blade design, and particularly relates to a turbine cooling blade pipe network topology data extraction method which is based on an NX design platform and comprises the following steps: importing 1, a turbine cooling blade model file; 2, creating a horizontal dividing surface, and dividing an exterior entity of the turbinecooling blade into a plurality of entities; 3, further segmenting each entity in the plurality of entities into a plurality of geometric units; 4, extracting position data of all geometric units; step 5, extracting topological connection relationship data among the geometric units; and 6, exporting the position data of all the geometric units and the topological connection relationship data amongthe geometric units. According to the turbine cooling blade pipe network topology data extraction method, the automation degree of blade design is increased, the turbine blade research and development period is shortened, and preparation is made for achieving blade modeling and analysis integration.
Description
Technical field[0001]The application belongs to the technical field of aero-engine turbine cooling blade design, and particularly relates to a method for extracting topological data of a turbine cooling blade pipe network.Background technique[0002]Turbine cooling blades are the core components of aeroengines and gas turbines. With the continuous increase of gas turbine inlet temperature, different forms of cooling structures are widely used in turbine cooling blades, and the blade cooling structure is becoming more and more complicated.figure 1 ,figure 2 The purpose is to control the temperature of the turbine blades within the allowable range of materials. On the other hand, the temperature gradient determines the thermal stress of the turbine blades. The reasonable arrangement of the cooling structure can effectively reduce the internal thermal stress of the blades and prolong the service life of the turbine blades.[0003]In order to ensure the reasonable selection and arrangement ...
