Finite Element Analysis of the Overturning Process of Ring-Stiffened Titanium Shperical-Cylindrica Diaphragm for Positive Expulsion Tanks

Abstract:

The shperical-cylindrica metal diaphragm model is established to simulate with finite element analysis method in the large displacement for the elastic-plastic theory, which is based on the current research on the metal diaphragm for positive expulsion tanks. It shows that the unsteady state on the position of rolling is the main reason for the failure of the diaphragm. Based on the optimization to metal diaphragm's structure, The ring-stiffened metal diaphragm model is established to reduce the unsteady state. The simulation result concludes that the optimization can reduce the unsteady state effectively, which also provides the reference for the improving design of metal diaphragm.
