This invention discloses a collaborative optimization design method for bearing systems based on TRIZ theory, belonging to the field of mechanical design and innovation methods. First, based on the optimization requirements of the bearing system performance, this invention establishes a three-level functional model of supersystem-system-subsystem and identifies key problem clusters. The functional model includes at least one of the following: useful functions, harmful functions, insufficient functions, and excessive functions. Then, based on the three-level functional model, contradiction solutions and resource analysis are performed at the component level, system level, and supersystem level to obtain contradiction solutions. Subsequently, a matter-field model is constructed and solved, and the TRIZ evolutionary law is applied to guide system reconstruction to obtain a system evolution scheme. Finally, the contradiction solutions and the system evolution scheme are cross-integrated and their feasibility is evaluated to generate an innovative conceptual design scheme for the bearing system. This invention effectively solves the problems of existing technologies being limited to single problems and isolated components.

This invention discloses a CAE simulation analysis method for misuse of die-casting trolleys, comprising: deriving a geometric model based on a preliminary design; dividing the element mesh; generating a finite element model; defining materials, boundary conditions, initial volumetric parameters, and control parameters; solving; viewing the analysis results; determining the usability of the model based on the analysis results; if not, improving the model and returning to the step of deriving the geometric model; if yes, determining whether the analysis results meet the design requirements; if yes, obtaining the final design; if not, obtaining the improved structure, obtaining the improved design based on the improved structure, and returning to the step of deriving the geometric model. This invention's CAE simulation analysis method for misuse of die-casting trolleys considers the strength performance of the trolley during the conceptual design stage. If the requirements are not met, it is immediately returned to the designer for modification or redesign, greatly shortening the physical experiment cycle and reducing costs.

This invention relates to the field of aircraft propulsion system technology, and discloses a comprehensive evaluation and decision-making method for multiple engine concept design schemes. By introducing game theory concepts, it achieves deep coupling of subjective and objective weights, and combines the maximum entropy criterion and deviation penalty factor to seek the optimal compromise between expert experience judgment and the inherent laws of data, thereby obtaining the optimal combination of weights. Based on this, a quantifiable comprehensive evaluation index is constructed to achieve a comprehensive and objective assessment and ranking of engine concept design schemes. Simultaneously, the Euclidean distance considering the standard deviation of technical indicators is introduced into the ranking of alternative schemes, enhancing the discriminative power and robustness of the evaluation results, effectively solving the problem of the difficulty in comprehensively balancing multiple technical indicators such as performance, structure, and cost. This invention can identify and screen the most promising innovative schemes, providing decision support for subsequent component design, thereby improving the overall engine performance and reasonably controlling R&D costs.
