Specifically, as shown in fig. 2, the apparatus 10 of the embodiment of the present invention includes: a parameter level principle design object modeler 100 and a structural design object manager 200 associated with the parameter level principle design object modeler. The parameter level principle design object modeler 100 is used for constructing and expressing a principle design object of a product, and is used as a management basis for a structural design object manager of an engine, a performance design process data of each component/subsystem and related design scheme data, wherein the structural design object manager is associated with the parameter level principle design object modeler in general; the structural design object manager 200 associated with the parameter level principle design object modeler is used to build and express structural design objects of a product as a management basis for engine three-dimensional structural solution models and structural analysis simulation process data.

(1) performance index attributes: if an object attribute is the function and performance index output by the expected product, the object attribute can be defined as the performance index attribute, and on the basis of the performance index attribute, the attribute can be used for accommodating requirement items and providing a verification basis for the performance design/simulation result. For example: the thrust-weight ratio, the oil consumption at a design point, the maximum length limit and the maximum diameter limit of the engine can be used as the performance index attributes of the overall design object of the engine.
(2) Working condition variables are as follows: an object property may be defined as a condition variable if it is an external condition parameter (e.g., an environmental parameter or a constraint parameter determined by other product components) that affects the performance of the product. For example: the flying M number, flying height, ground atmospheric pressure and temperature of the engine can be used as working condition variables of the overall design object of the engine.
(3) Designing attributes: an object property can be defined as a design property if it is a parameter given by the designer that affects the logical logic and performance of the product or product component (e.g., a geometric design parameter of the product); a change in the value of a design attribute will result in the state of the art in which the principle design object generates a new version. For example: the number of fan stages, the number of compressor stages, the inlet diameter, the inlet hub ratio, the boost ratio, the pre-turbine temperature, etc. of the engine can be defined as the design attributes of the overall engine design object.

(3) critical feature dimensions from three-dimensional geometric models: if a structural design object has a part three-dimensional model, a key characteristic dimension for representing the technical state of the part is determined, and if the structural design object has a part three-dimensional model, a key assembly dimension for representing the technical state of the part is determined; in the data management architecture of the engine Design simulation platform, a plug-in program which is embedded and integrated with CAD (Computer Aided Design) software (such as UG NX) is responsible for automatically scanning and extracting the geometric dimension parameters from the three-dimensional structural model of the part.
In addition, the structure design object modeler specifically functions as follows:
(1) providing a structural object definition and management tool, defining independent definition structural design object hierarchical relation in a dragging mode, and automatically extracting the type and assembly hierarchical information of parts from an engine three-dimensional structural scheme model established based on NX through a 'structural collaborative design real-time manager embedded and integrated with NX software' to generate a corresponding structural design object hierarchy;
