复杂装备多域均衡的性能增强设计理论、方法及应用研究

The complex equipment has complex composition structure, numerous component parameters, and associated coupling modules. Aiming to tackle the design difficulty such as more diverse customized demands, more integrated function and structure, more enhanced performance indicators. An extensive research is proposed “Theory, method and application research on performance enhancement design of complex equipment using multi-domain equilibrium”. The study includes five aspects: the first is performance enhancement design of transplant variation and accurate response using rational equilibrium in demand domain, it tackles the difficulty of inaccurate response to demands; the second is performance enhancement design of decomposition reconstruction and decoupling association using orderly equilibrium in function domain, it tackles the difficulty of hierarchical decoupling; the third is performance enhancement design of non-standard variation and linkage optimization using robust equilibrium in structure domain, it tackles the difficulty of structure variation and regeneration; the forth is performance enhancement design of machine matching and variation tolerance to working conditions using recursive equilibrium in process domain, it tackles the difficulty of performance fluctuation instability; the fifth is platform development and application validation of performance enhancement design using multi-domain equilibrium. The research has three innovations: the first is multi-domain linkage performance enhancement design using extraction and equilibrium of inter-constraint factors; the second is customized demand extension and accurate response design using cross-domain bi-directional mapping; the third is multi-scale matching and tolerant optimal robust design using dynamic extension. The proposed theory and method will be verified by precision CNC machine tools and other complex equipment.
