Analysis for Fluid-Structure Coupling Analysis of Cryogenic Tank
In transportation,the various road conditions make the medium within the cryogenic tank slosh-ing and the dynamic load caused by the sloshing becomes into one of the main loads in analyzing this cryo-genic tank.In order to further analyze both safety and reliability of the cryogenic tank optimized,the maxi-mum impact force produced by the medium sloshing and the wall pressure while the maximum impact force were extracted were considered,including having the unidirectional fluid-solid coupling method adopted to analyze the structural stress strength of this cryogenic tank optimized.The results show that,the maximum stress calculated by the fluid-solid coupling method stays at the fixed end cylinder still and it complies with the result calculated by the static analysis average pressure method,but the maximum stress value of the inner cylinder increases by 18.4%,which indicates that the fluid-solid coupling method can predict the stress state of the cryogenic tank more accurately than the static analysis average pressure method.
