【摘要】在医疗技术、环境保护/分析、实验室或工艺工程中，机械驱动的隔膜泵的使用变得不可或缺。它们的无油、无维护、无污染操作等特殊特性使它们适合于许多应用领域。本研究的目的是找出隔膜前后移动的反作用力。在这个数量的载荷步骤中，涉及到在隔膜上施加不同压力的前进和收缩行程，并计算出施加在隔膜上的应力。通过全局有限元分析，得到了关键构件的应力和反作用力的位移值，最终得出该结构是安全的，具有足够的安全裕度。

[Abstract] In wide range of applications like in medical technology, environmental protection/analysis, in the Laboratory or process engineering the use of mechanically driven diaphragm pumps became indispensable. Their particular properties such as oil-free, maintenance-free and uncontaminated operation make them suitable for numerous fields of application. The objective of the present work is to find out the reaction forces to move the diaphragm in forward and backward direction. In this number of load steps are involved in forward and retraction strokes with varying pressure applied on the diaphragm and Calculated the stress imparted on the diaphragm. A global finite element analysis is carried out to arrive at the values of stresses and displacements in critical components and reaction forces, finally from the results it is concluded that the structure is safe and has an adequate margin of safety.
