摘要: 强耦合轴承、密封、平衡盘等部件的高速涡轮泵转子在设计过程需要处理不同领域的信息,如摩擦学、动力学、流体力学等学科的信息。为实现对这些多源信息的解耦和知识融合,提出基于公理设计的高速涡轮泵设计方法。该方法实现了对高速涡轮泵动力学设计的四层次功能需求域(Functional requirements, FRs)分解及其设计参数域(Design paramenters, DPs)映射,将14个DPs集成在5个物理部件(轴承、端面密封、推力轴承、平衡盘、转子)中,并由此发展了14×14的公理设计矩阵;由此矩阵获得了基于多源信息耦合的涡轮泵转子动力学设计顺序的流程图;对在该设计方法的指导中完成了对某涡轮泵转子的动力学设计,并对设计结果进行了评估。结果显示提出的基于公理设计方法优化了高速涡轮泵动力学设计过程和结果。

Abstract: The strong coupling design information from the different parts (such as bearings, seals, balance disc, etc) and the different fields (such as tribology, dynamics, fluid dynamics, etc) need to be addressed for finishing the design of an advanced high-speed turbopump rotor dynamics. For decoupling and integrating all of the multi-source information, the design method based on the axiomatic design method is proposed. The four levels of the functional requirements (FRs) and the design parameters (DPs) mapping for the high-speed turbopump rotor dynamics design process is developed, and the 14 DPs are integrated in the 5 parts of the rotor system, such as journal bearings, seal, thrust bearing, balance disc, and shaft. The 14×14 design matrix is built. With the design matrix, the flow chart for the multi-source information coupled dynamics design method is obtained. A design case for a turbopump rotor dynamics is completed, and the major requirements are assessed. The results show the axiomatic design method for the high-speed turbopump rotor optimizes the dynamics design process and results.
