Abstract：The process of liquid sloshing in the braking process of tank truck was studied with FLUENT,and the stress of tanker was simulated with ANSYS based on the condition of the maximum water hammer pressure.The results showed that the maximum stress calculated by the hammer pressure in the actual braking process of tank truck could be increased by 38.6% compared with the maximum stress of liquefied gas tank container calculated by JBT 4781—2005 standards.Moreover,the stress of tanker was lower than allowable stress according to JBT 4781—2005 standards.But the stress of the junction of support ring and head was greater than allowable stress calculated by the hammer pressure during the actual braking process of tank truck.It could not meet the strength requirement.
