| 为了丰富隔膜泵隔膜设计理论,优化隔膜结构及受力状态以提高隔膜疲劳寿命,采用流体动力学数值模拟的方法完成隔膜的优化设计。文中建立了碟形隔膜结构形状的参数化控制模型并从系统化的角度出发,充分考虑系统对隔膜运动、变形的影响,对不同控制参数下的隔膜泵液力端进行流固耦合数值模拟以求得隔膜的应力状态。以此为基础得到了新的隔膜设计理论。建立的控制模型实现了碟形隔膜设计的参数化控制,对隔膜泵液力端的流固耦合数值模拟,充分体现了现代设计理论系统化的优点。采用的方法推进了现代设计理论在隔膜泵设计领域的运用,同时得出的结论对隔膜的设计也有着很大使用价值。 |

| In order to enrich the theory of diaphragm design for diaphragm pump, optimize the diaphragm structure and stress state to improve its fatigue life, the fluid dynamics numerical simulation method was used to complete the optimization design of the diaphragm. In this paper, the dish-shaped diaphragm structure shape control model was established and from the perspective of systematic, fully considering the system influence on the deformation of diaphragm movement, the stress state of diaphragm under different control parameters was work out by fluid-structure interaction numerical simulation for diaphragm pump hydraulic end. On this basis, the new diaphragm design theory was established. The established control model is the first one for the dished parameterized control of diaphragm design, the fluid- structure interaction numerical simulation for diaphragm pump hydraulic end, fully embodies the advantages of modern design theory -systematization. The methods drive the application of modern design theory in the field of diaphragm pump design, at the same time the conclusion for the design of the diaphragm also has the very practical value. |
