Burst Pressure Research Of Influence Factors On Reverse Arch Rupture Disc

Reverse arch rupture disc is a kind of safety relief apparatus of pressure vessels.The burst properties of reverse arch rupture are a matter of great concern in the engineering industry.Therefore,in this paper,the performance test platform of reverse arch rupture disc was built.The method of experiment and simulation were carried out to research the influence of arch height,heat treatment and fillet radius on the burst pressure of reverse arch rupture disc.The research of reverse arch rupture disc has great values for engineering and manufacturing.The main contents and results of this paper are as follows:(1)The apparatus for experiment of forming and blasting test of reverse arch rupture disc were constructed,which can record displacement and pressure in the process of experiment.The relationships between the arch height and the forming pressure,arch height and the burst pressure are studied through experiment.And the formula of the forming pressure and the optimum ratio of arch height to diameter are proposed.(2)Solution treatment experiments of reverse arch rupture disc are carried out to explore the effects of solution temperature and holding time on the burst pressure of reverse arch rupture disc,in addition,the heat treatment characters of reverse arch rupture disc are analyzed according to the effects research of solution treatment on material of 316L.(3)Numerical simulation is applied to analysis the stress and strain distribution of the reverse arch rupture disc critical state,and to study the influence of fillet radius on the burst pressure and stress distribution.The results show that the fillet radius can be obtained better stress distribution and unstable position in the range of 0.4mm-0.8mm.
