Dynamic Burst Pressure Prediction of Gas Cylinder
摘要
Abstract
During the process of accident analysis of the gas cylinder explosion the burst pressure was of-ten needed to predict.HP295 steel for the gas cylinders was studied.The dynamic mechanical properties were tested and the strain rate effect was found through the tests.Finite element model was established with the dynamic experimental results.The dynamic burst process was simulated with the result that the rupture occurred on the barrel rather than on the head.With the increase of loading rate,the burst pres-sure simulated by the finite element analysis is more and more close to that calculated by the adjusted Barlow formula.As a result under rapid dynamic loading conditions the formula can be used to predict the burst pressure.关键词
