The purpose of this paper is to provide reference for safety warning and accident recovery of tank truck rollover.In this paper,two methods are presented to solve the critical lateral acceleration of tank truck rollover considering liquid sloshing.One method is step steer simulation method.The liquid sloshing is simplified to two-dimensional liquid sloshing.The change of liquid center of gravity is used to be equivalent to the effect of liquid sloshing on tank truck rollover.The critical lateral acceleration of tank truck considering liquid sloshing is studied by combining analytical method and multi-body dynamics simulation method.The other method is collaborative simulation method.The rollover of tank truck is studied through the collaborative simulation of ADAMS CAR,SIMULINK and FLUENT.This method overcomes the traditional simulation method which does not consider the coupling effect between tank truck movement and liquid sloshing in the rollover process,simulates the rollover process of tank truck more truly,and calculates the critical value of tank truck rollover more accurately.
