压缩机舌簧阀组的公理化设计

Axiomatic Design of the Reed Valve Components of Compressor

压缩机气阀的设计涉及到很多设计要素,各要素之间相互耦合,影响着气阀设计的成败。如果只针对气阀的某个要素分别进行研究,这样局部零部件的优化设计未必使得气阀整体性能得到提高。因此,本文应用公理设计理论,以吸气阀为例,将阀片和相关的阀孔及阀座作为一个组件进行设计,系统地分析气阀的功能需求,并映射出与之相对应的设计参数,经独立公理和信息最少公理优化后得到最终的CAD模型,通过样机测试后证明是可靠有效的。这种设计方法可以在设计初期就预测出设计的结果,并选择合理的设计方案,为气阀的优化设计提供了一种可行的方法。

The design of valve components of compressors focuses on the study of the individual parts of the system,which leads to the partial optimization instead of the whole.Taking the suction valve as an example,the reed and the plate are considered as an integrated system,the FRs and the DPs of the system are analyzed by using Axiomatic design,and a multi-level roadmap is presented in this paper.After the optimization,a CAD model of the system is obtained,its validity is indentified by the testing.
