摘　　要：应用FLUENT软件对罐车在刹车过程中罐内液体的晃动情况进行模拟,并基于最大水击压力工况,运用有限元分析软件ANSYS对罐车进行应力分析。研究表明:按实际刹车制动过程液体晃动水击内壁压力计算的液化气体罐式集装箱的罐体最大应力要比按JBT 4781—2005标准计算的最大应力值增加38.6%。而且按照JBT4781—2005液化气体罐式集装箱规定计算得出的罐体各部分应力均低于许用值;但是在实际液体晃动产生的水击压力作用下,在支撑圈与封头连接处的应力大于许用值,不能满足强度要求。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.
