Finite Element Analysis of Large Diaphragm Pump Rubber Diaphragm

In allusion to the work process for a diaphragm of diaphragm chamber,a simplified two-dimensional axisymmetric finite element model of membrane structure was established,and laid bare the implicit dynamics analysis,while a three-dimensional symmetrical structure whole finite element model of the diaphragm chamber and diaphragm was established and laid bare the analysis for fluid-solid coupling.At last,for two different methods and results began comparison in order to elicit a reasonable numerical simulation method which will be used to simulate the changes on stress and displacement of diaphragm movement,so as to guide reasonable diaphragm design.
